A direct-attached storage (DAS) enclosure adds drive bays to a computer without requiring a network storage setup. My best overall pick is the TERRAMASTER D6-320, which offers six bays for buyers who want room to expand. The UGREEN 5-Bay USB-C DAS stands out for its range of RAID modes, while the TerraMaster D2-320 is a simpler fit for a two-drive setup. The main tradeoffs are bay capacity, RAID flexibility, connection speed, cooling, and how much setup control you want. Read on for the full comparison and help matching an enclosure to your drives and workflow.

Key Takeaways
- The TERRAMASTER D6-320 leads for expansion: its six bays give growing storage collections more headroom than the four- and five-bay options, though a larger enclosure may be more than a small setup needs.
- The UGREEN 5-Bay stands out for RAID choice: its eight RAID modes offer more ways to balance capacity and redundancy than a basic multi-bay enclosure, but buyers should understand their chosen mode before loading important files.
- Two-bay models suit focused setups: the TerraMaster D2-320 and CENMATE dual-bay options take less drive space than six-bay units, while limiting future expansion.
- Connection labels do not tell the whole speed story: USB-C or USB 3.2 naming should be weighed against the computer port, cable, drives, and workload; the slowest link can limit transfers.
- Cooling and drive fit separate otherwise similar picks: several CENMATE models include cooling fans, while the ORICO 5-Bay model explicitly accommodates both 2.5- and 3.5-inch drives, so check your drive sizes and noise tolerance before choosing.

TERRAMASTER D6-320 6-Bay External Hard Drive Enclosure (Diskless)
I’d choose the TERRAMASTER D6-320 when the priority is keeping six individual drives connected through one enclosure. Its USB 3.2 Gen 2 link reaches 10Gbps, twice the stated bandwidth of the CENMATE 6-Bay, which can help when moving large files, though actual speeds depend on the drives and computer. The temperature-controlled fan and hot-swap support also suit a working archive that needs routine drive changes. The main tradeoff is its individual-disk-only design: unlike the UGREEN 5-Bay, it offers no RAID modes, so it does not combine drives into a protected or unified array. I’d shortlist it for expansion and straightforward access, but skip it if you want redundancy managed by the enclosure. Drives must be supplied separately.
Pros:- Six bays support up to 132TB total with compatible drives
- USB 3.2 Gen 2 offers up to 10Gbps bandwidth
- Hot swapping and plug-and-play support simplify drive changes
- Temperature-controlled cooling adjusts to drive temperature
Cons:- Does not support RAID or other disk arrays
- Diskless design means drives are not included
Best for: Video editors and archive owners who need up to six independently accessible SATA drives and a 10Gbps USB connection
Not ideal for: Buyers who need enclosure-managed RAID, NAS features, or an included set of drives
- Bays:6
- Drive compatibility:2.5-inch and 3.5-inch SATA HDDs; 2.5-inch SATA SSDs
- Maximum capacity:22TB per drive; 132TB total
- Interface:USB Type-C, USB 3.2 Gen 2
- Maximum transfer rate:10Gbps
- Operating systems:Windows, Mac, Linux
- Enclosure material:Metal
- Dimensions:8.58 x 5.12 x 8.9 inches
- RAID support:Not supported
Our verdict“Pick the D6-320 for six-drive capacity and faster USB bandwidth when individual disks meet your storage plan.”
CENMATE 6-Bay Aluminum Hard Drive Enclosure with Cooling Fans, USB 3.0, and Hot-Swap Support
The CENMATE 6-Bay is a fit for buyers who want six drive slots and the option to link multiple enclosures. It supports daisy chaining for up to three devices, giving a storage setup room to grow without replacing the original unit. Compared with the TERRAMASTER D6-320, its USB 3.0 connection is limited to 5Gbps rather than 10Gbps, so large transfers may take longer; in return, tool-free installation keeps drive swaps simple. Two fans help cool a populated enclosure, but their stated 40–50 dB noise may be noticeable in a quiet office or living room. I’d consider this model for a multi-enclosure desk setup, not for RAID: it supports neither RAID nor NAS, and drives are sold separately.
Pros:- Six bays support drives up to 20TB each
- Daisy-chain support connects up to three devices
- Tool-free installation and hot swapping simplify drive changes
- Aluminum construction and two fans provide a cooling-focused enclosure
Cons:- USB 3.0 is limited to a stated 5Gbps
- Fans produce around 40–50 dB of noise
- Does not support RAID or NAS
Best for: Home media archivists who want six SATA bays now and the option to daisy-chain more enclosures later
Not ideal for: Noise-sensitive users or anyone who needs RAID, NAS functionality, or faster-than-5Gbps USB bandwidth
- Drive bays:6
- Supported drives:2.5-inch and 3.5-inch SATA HDDs and SSDs
- Maximum capacity:Up to 20TB per drive
- Interface:USB 3.0; USB-A/USB-C cable
- Maximum transfer speed:Up to 5Gbps
- Cooling:Two 2.7-inch fans
- Fan noise:Around 40–50 dB
- Daisy-chain expansion:Up to 3 devices; up to 360TB stated
- RAID/NAS:Not supported
Our verdict“Choose this CENMATE for expandable six-drive direct storage if 5Gbps bandwidth and audible fans suit your setup.”
CENMATE 3-Bay Aluminum Hard Drive Enclosure with Cooling Fan
With three bays and a stated 60TB total capacity, the CENMATE 3-Bay sits between small two-drive enclosures and six-bay towers. That makes it a practical middle ground for someone consolidating a few backup or media drives without committing to a larger footprint. It shares the 5Gbps USB 3.0 limit and tool-free, hot-swap access of the CENMATE 6-Bay, but takes fewer drives and occupies a more compact 7.95 × 5.2 × 4.41-inch shell. Daisy chaining provides a path to add compatible storage later. The tradeoffs are its lack of RAID or NAS support and a fan rated around 40–50 dB; I’d keep it away from a quiet listening or sleeping area. It is also diskless.
Pros:- Three bays support up to 60TB total capacity
- Tool-free installation and hot swapping ease drive changes
- Aluminum housing and a cooling fan support everyday drive use
- USB-A and USB-C connectivity with daisy-chain support
Cons:- USB 3.0 transfer rate is limited to 5Gbps
- Fan noise is approximately 40–50 dB
- Does not support RAID or NAS
Best for: A home user consolidating up to three SATA drives who wants a smaller desktop DAS with simple drive swaps
Not ideal for: Buyers planning a six-drive archive, requiring RAID or NAS, or placing storage beside a noise-sensitive workspace
- Drive bays:3
- Supported drive sizes:2.5-inch and 3.5-inch SATA HDDs and SSDs
- Maximum capacity:20TB per drive; 60TB total
- Interface:USB 3.0
- Data transfer rate:Up to 5Gbps
- Connectivity:USB-A and USB-C
- Material:Aluminum alloy
- Dimensions:7.95 × 5.2 × 4.41 inches
- RAID/NAS support:Not supported
Our verdict“Pick this three-bay model for a modest drive collection when you want easier expansion than a two-bay enclosure.”
UGREEN 5-Bay USB-C DAS Enclosure with 8 RAID Modes
The UGREEN 5-Bay stands apart from the diskless TerraMaster and CENMATE models by offering eight storage modes, including RAID 0, 1, 3, 5, and 10. That gives buyers a way to balance capacity, performance, or redundancy through the enclosure, though changing modes requires backing up and reformatting data. Its five bays and 160TB stated ceiling leave room for a substantial library, while temperature-based fan control and drive status LEDs help with routine oversight. The compromise is a 5Gbps USB connection: the TERRAMASTER D6-320 has a faster 10Gbps link and an extra bay, but no RAID at all. I’d pick UGREEN when RAID matters more than peak interface bandwidth. It remains direct-attached storage, not a NAS pool.
Pros:- Eight storage modes include RAID 0, 1, 3, 5, and 10
- Five bays support up to 160TB total capacity
- Temperature-based fan control responds to drive temperatures
- Drive status LEDs aid everyday monitoring
Cons:- USB-C connection is limited to 5Gbps
- Changing RAID modes requires data backup and reformatting
- Cannot be managed as part of a NAS storage pool
Best for: Desktop storage users who want multiple enclosure-managed RAID choices across up to five SATA drives
Not ideal for: Buyers who need NAS storage pooling, faster-than-5Gbps USB, or frequent RAID-mode changes without reformatting
- Bays:5
- Drive compatibility:2.5-inch and 3.5-inch SATA HDDs and SSDs
- Maximum capacity:160TB total; up to 32TB per drive
- Storage modes:PM, RAID 0, RAID 1, RAID 3, RAID 5, RAID 10, Large, Clone
- Interface:USB-C, USB 3.2 Gen 1
- Maximum transfer rate:5Gbps
- Compatible operating systems:Windows, macOS, Linux
- Dimensions:9.06 × 5.37 × 7.09 inches
- Power adapter:12V/8A DC
Our verdict“Choose the UGREEN if enclosure-managed RAID is a higher priority than 10Gbps connectivity or NAS integration.”
CENMATE Aluminum 2-Bay USB 3.2 Gen 2 Hard Drive Enclosure with Cooling Fan
For a compact setup, the CENMATE 2-Bay offers a useful combination of two SATA slots and a 10Gbps USB 3.2 Gen 2 connection. That is the same stated interface speed as the six-bay TERRAMASTER D6-320, but with room for just two drives; the smaller drive count suits a focused backup pair or working files without a large enclosure. Tool-free installation and hot swapping simplify changes, while daisy chaining can connect up to three devices, with up to 120TB stated across them. There are limits: it has no RAID or NAS support, and the built-in fan is rated around 40–50 dB. I’d favor it for compact direct storage, but buyers building a larger archive should compare it with the three- or six-bay options.
Pros:- USB 3.2 Gen 2 supports transfer speeds up to 10Gbps
- Two bays accept 2.5-inch and 3.5-inch SATA drives
- Tool-free installation and hot swapping support quick drive changes
- Daisy chaining supports up to three devices
Cons:- Two bays offer less direct capacity than the three-, five-, and six-bay options
- Fan noise is around 40–50 dB
- Does not support RAID or NAS
Best for: Laptop and desktop users who need two SATA drives, 10Gbps USB, and a smaller DAS footprint
Not ideal for: Buyers building a large multi-drive archive or seeking RAID, NAS, or quiet fan operation
- Drive bays:2
- Compatible drives:2.5-inch and 3.5-inch SATA HDDs and SSDs
- Maximum capacity:20TB per drive
- Interface:USB 3.2 Gen 2, USB-A/USB-C
- Maximum transfer speed:Up to 10Gbps
- Cooling:Built-in 2-inch fan
- Fan noise:Around 40–50 dB
- Daisy-chain capacity:Up to 120TB across 3 devices
- RAID/NAS support:No
Our verdict“Choose this CENMATE for a two-drive setup where compact size and 10Gbps USB matter more than RAID or added bays.”
ORICO 5-Bay RAID External Hard Drive Enclosure
Hardware RAID flexibility gives this five-bay ORICO a different job from the SABRENT DS-SC5B, which keeps drives independent and has no RAID. This model offers RAID 0, 1, 3, 5, and 10 alongside JBOD, Clone, and Clear, so it can suit buyers who want array options without adding a separate RAID controller. Support for both 2.5-inch and 3.5-inch SATA drives also makes it easier to mix drive formats. The built-in 150W supply keeps the power setup self-contained, while the 80mm fan and vented shell support sustained operation. The tradeoffs are USB 3.0 rather than 10Gbps USB-C, and a stated 110TB ceiling; the title’s 130TB claim conflicts with the supplied capacity details. Drives are not included.
Pros:- Hardware RAID options include RAID 0, 1, 3, 5, and 10
- Accepts both 2.5-inch and 3.5-inch SATA HDDs and SSDs
- Built-in 150W power supply avoids an external power brick
- 80mm fan and venting support extended drive operation
Cons:- USB 3.0 is slower on paper than the 10Gbps USB-C connection on the SABRENT DS-SC5B
- Supplied description caps total capacity at 110TB, despite the title’s conflicting 130TB claim
- Drives are not included
Best for: Desktop storage builders who want five SATA bays and several hardware RAID modes in one USB-connected enclosure.
Not ideal for: Buyers prioritizing 10Gbps USB-C transfers or a clearly documented capacity above 110TB.
- Drive bays:5
- RAID modes:RAID 0, 1, 3, 5, 10, JBOD, Clone, Clear
- Drive compatibility:2.5-inch and 3.5-inch SATA HDDs and SSDs
- Maximum capacity:22TB per drive; 110TB total
- Interface:USB 3.0 Type-A
- Maximum transfer rate:230MB/s
- Power supply:Built-in 150W
- Cooling:80mm fan with front and rear honeycomb vents
- Compatibility:Windows, Mac, Linux
Our verdict“Choose this ORICO if you want five bays with several built-in RAID modes and can work within its stated 110TB capacity.”
SABRENT 5-Bay USB-C 10Gbps 3.5-Inch Hard Drive Enclosure and DAS Dock (DS-SC5B)
10Gbps USB-C and five independently connected bays make the SABRENT a strong fit for users who want quick access to separate drives. Unlike the ORICO 5-Bay RAID External Hard Drive Enclosure, it does not combine drives into hardware RAID; each bay remains individually addressable. That distinction suits archives, rotating backups, and workflows where drives need to be swapped or powered separately. Its tool-free hot-swap bays, per-bay switches, and activity LEDs make day-to-day handling more direct, while the temperature-controlled 120mm fan adjusts cooling to drive conditions. This is a substantial, 10-pound enclosure, and its 100TB stated limit is below the ORICO’s 110TB. It is also diskless and offers no NAS function, so network access or array management requires other equipment.
Pros:- Five independent bays over USB-C at up to 10Gbps
- Tool-free hot-swap bays with per-bay power switches
- Temperature-controlled 120mm PWM fan
- Activity LEDs show drive status
Cons:- No RAID or NAS functionality
- Supports 3.5-inch drives only
- At 100TB, its stated capacity is lower than the 110TB ORICO five-bay models
Best for: Video editors and archivists who need five individually accessible drives, fast USB-C connectivity, and frequent drive swaps.
Not ideal for: Buyers who need hardware RAID, NAS access, or support for 2.5-inch drives.
- Drive bays:5
- Supported drives:3.5-inch SATA HDDs or SSDs
- Maximum capacity:100TB (5 × 20TB)
- Interface:USB-C, USB 3.2 Gen 2
- Data transfer rate:Up to 10Gbps
- RAID:Not supported
- Cooling:120mm PWM temperature-controlled fan
- Dimensions:10.4 × 5.9 × 7.3 inches
- Compatibility:Windows, macOS, Linux
Our verdict“Pick the SABRENT for fast USB-C access to five separate 3.5-inch drives when RAID and network sharing are not required.”
TerraMaster D2-320 2-Bay USB RAID Enclosure
For a smaller storage setup, the TerraMaster D2-320 keeps RAID choices straightforward: RAID 0, RAID 1, JBOD, or single-drive mode across two bays. Compared with the five-bay ORICO 5-Bay RAID External Hard Drive Enclosure, it gives up expansion room and several array modes, but takes less space and still supports up to 44TB total. Its 10Gbps USB 3.2 Gen 2 connection is also faster on paper than that ORICO’s USB 3.0 link. Tool-free installation and a temperature-controlled fan reduce setup and cooling fuss for a desktop pair of drives. The enclosure is diskless and plastic, and it is direct-attached storage rather than a NAS. Buyers planning a larger array or a network-accessible library should look at a multi-bay alternative.
Pros:- RAID 1 supports a two-drive mirrored setup
- 10Gbps USB 3.2 Gen 2 interface
- Tool-free drive installation with locking trays
- Temperature-controlled fan adjusts to drive temperature
Cons:- Two bays limit expansion compared with the five-bay ORICO and SABRENT models
- Plastic enclosure rather than an aluminum shell
- Diskless DAS design does not provide NAS functionality
Best for: Home users setting up a two-drive backup or mirror who want simple RAID modes and a compact USB-C-speed desktop enclosure.
Not ideal for: Storage builders expecting to grow beyond two drives or share files over a network without a host computer.
- Drive bays:2
- Drive compatibility:2.5-inch and 3.5-inch SATA HDDs; 2.5-inch SATA SSDs
- Maximum capacity:22TB per drive; 44TB total
- RAID modes:RAID 0, RAID 1, JBOD, SINGLE
- Interface:USB 3.2 Gen 2
- Maximum transfer rate:10Gbps
- Dimensions:8.74 × 4.69 × 6.06 inches
- Weight:1.3kg
- Enclosure material:Plastic
Our verdict“Choose the D2-320 for a compact two-drive RAID setup, especially when mirroring matters more than bay count.”
CENMATE 4-Bay USB 3.2 Gen 2 SATA HDD/SSD Enclosure with Cooling Fan
The CENMATE offers four hot-swappable bays for 2.5-inch or 3.5-inch SATA drives, a useful middle ground between the two-bay TerraMaster D2-320 and five-bay options such as the SABRENT DS-SC5B. USB-A and USB-C connections at up to 10Gbps make it flexible to connect, while the aluminum alloy body and built-in fan provide cooling for a populated enclosure. Its tool-free design helps when drives need to be replaced or moved between projects. The key compromise is simplicity: this is direct-attached storage without RAID or NAS, so data organization and redundancy depend on the computer and the drives. The listed fan noise of around 40–50 decibels may also make it a poor match for a quiet desk, and actual transfer speeds depend on the connected hardware.
Pros:- Four bays support 2.5-inch and 3.5-inch SATA HDDs and SSDs
- USB-A and USB-C connections support up to 10Gbps
- Hot-swap, tool-free drive handling
- Aluminum alloy construction with built-in cooling fan
Cons:- No RAID or NAS functionality
- Listed fan noise is around 40–50 decibels
- Actual transfer speeds depend on the drives and host computer
Best for: Desktop users who need four hot-swappable SATA drives, including both 2.5-inch and 3.5-inch models, without RAID.
Not ideal for: Buyers who need hardware RAID, NAS access, or a quiet enclosure for a nearby workspace.
- Drive bays:4
- Drive compatibility:2.5-inch and 3.5-inch SATA HDDs and SSDs
- Maximum capacity:20TB per drive; 80TB total
- Interface:USB 3.2 Gen 2, USB-A and USB-C
- Maximum transfer speed:Up to 10Gbps
- Cooling:Built-in 2-inch fan
- Construction:Aluminum alloy
- Storage type:DAS; no RAID or NAS
Our verdict“Choose this CENMATE when four flexible, hot-swappable bays matter more than RAID features or quiet operation.”
ORICO 5-Bay Hard Drive Enclosure for 2.5- and 3.5-Inch Drives
With five SATA bays and up to 110TB stated capacity, this ORICO suits buyers who want to add a large pool of drives over a basic USB 3.0 connection. Its magnetic cover and tool-free access make drive installation less involved than on setups that require separate trays, and the 60mm fan helps move air through the enclosure. Compared with the newer SABRENT DS-SC5B, this model supports both 2.5-inch and 3.5-inch drives and lists a higher total capacity, but its USB 3.0 Type-B interface tops out at 5Gbps rather than 10Gbps USB-C. It also lacks stated RAID modes, so it is better suited to separately managed storage than an array. Linux support has a specific limitation: only one drive can be read at a time.
Pros:- Five SATA bays with up to 110TB stated total capacity
- Supports both 2.5-inch and 3.5-inch drives
- Tool-free magnetic cover simplifies drive access
- 60mm fan and listed protection features
Cons:- Linux can read only one drive at a time
- USB 3.0 Type-B is limited to a stated maximum of 5Gbps
- No RAID functionality is listed
Best for: Linux and desktop users expanding a large SATA drive collection who value five bays and easy drive access over RAID.
Not ideal for: Linux users who need simultaneous access to multiple drives, or buyers seeking RAID and faster USB-C connectivity.
- Drive bays:5
- Supported drive sizes:2.5-inch and 3.5-inch SATA
- Maximum capacity:22TB per drive; 110TB total
- USB interface:USB 3.0 Type-B
- Maximum transfer rate:5Gbps
- Cooling:60mm double-ball-bearing fan
- Dimensions:8.6 × 5.5 × 7.7 inches
- Weight:2.2kg
- Enclosure material:Plastic
Our verdict“Pick this ORICO for high-capacity five-bay expansion and simple drive access if its USB 3.0 link and Linux limit fit your setup.”
TerraMaster D4-320 4-Bay External Hard Drive Enclosure (Diskless)
The TerraMaster D4-320 is my strongest all-around choice for a DAS enclosure when the goal is adding several independent drives without introducing RAID management. Its USB 3.2 Gen 2 10Gbps connection is twice the stated link speed of the ORICO 5-Bay USB-C Hard Drive Enclosure, while four bays and a 120TB stated ceiling offer room for a substantial library. Tool-free trays and hot swapping make drive changes easier, and the temperature-controlled fan plus vibration damping address the heat and noise that can build up in a multi-drive box. The tradeoff is deliberate simplicity: there is no RAID, so it cannot provide enclosure-level redundancy or combine drives into an array. It is also diskless, and its four bays offer less expansion than six-bay alternatives in this roundup.
Pros:- USB 3.2 Gen 2 offers a 10Gbps connection
- Supports up to 120TB across four drives
- Tool-free trays and hot swapping simplify drive replacement
- Temperature-controlled cooling and vibration damping help manage heat and noise
Cons:- Does not support RAID

ORICO 5-Bay USB-C Hard Drive Enclosure
For buyers who want five bays in a compact enclosure, this ORICO adds room for one more drive than the TerraMaster D4-320 and lists up to 110TB total capacity. That makes it a practical fit for a growing collection of mixed 2.5-inch and 3.5-inch SATA drives. The tradeoff is connection speed: its USB 3.2 Gen 1 link tops out at 5Gbps, half the stated 10Gbps rate of the D4-320, so it is less compelling when moving large files quickly is the priority. Plug-and-play setup, a quiet 80mm fan, and an included power adapter keep the basic setup simple. As with the TerraMaster, this is diskless, and the supplied data does not list RAID support; capacity also depends on compatible drives.
Pros:- Five bays provide more drive slots than the four-bay TerraMaster D4-320
- Supports both 2.5-inch and 3.5-inch SATA drives
- Quiet 80mm fan supports drive cooling
- Includes a 12V/10A power adapter and plug-and-play USB-C connectivity
Cons:- USB 3.2 Gen 1 is limited to 5Gbps, below the TerraMaster D4-320’s 10Gbps link
- Drives are not included
- Maximum capacity depends on compatible drives
Best for: Home archivists who need five SATA drive slots and value simple USB-C setup over a 10Gbps connection
Not ideal for: Users who routinely move large files at high speed or want confirmed RAID support in the enclosure
- Bays:5
- Drive compatibility:2.5-inch and 3.5-inch SATA
- Maximum capacity:22TB per drive; 110TB total
- Interface:USB 3.2 Gen 1, USB-C
- Maximum transfer speed:5Gbps
- Read/write speed:Up to 260 MB/s
- Power supply:12V/10A
- Cooling:80mm fan
- Dimensions and weight:3.7 x 5.77 x 8 inches; 1.6 pounds
Our verdict“Pick this ORICO if five drive slots matter more than the faster connection offered by the TerraMaster D4-320.”
CENMATE 4-Bay Aluminum Hard Drive Enclosure with Cooling Fan
The CENMATE makes the most sense when a buyer wants four bays and basic drive access without paying for features beyond a direct-attached enclosure. It supports up to 80TB total and connects over USB 3.0 Type-A or Type-C at up to 5Gbps under UASP. Tool-free access and hot swapping put it on familiar ground with the faster TerraMaster D4-320, but the CENMATE has a lower listed capacity ceiling and a slower connection. Its aluminum body and included fan help with heat, though the stated 40–50 dB fan noise may be noticeable in a quiet office. There is no RAID or NAS support, so this is best for users who will manage drives through their computer and do not need enclosure-level storage features.
Pros:- Four bays support up to 80TB total capacity
- Accepts 2.5-inch and 3.5-inch SATA HDDs and SSDs
- USB Type-A and Type-C connections support up to 5Gbps under UASP
- Tool-free hot swapping and aluminum construction simplify use and help manage heat
Cons:- Fan noise is specified at about 40–50 dB
- No RAID or NAS support
- Its 5Gbps link is slower than the TerraMaster D4-320’s 10Gbps connection
Best for: Budget-conscious desktop users who need four SATA drive slots for separate backups or a media library
Not ideal for: Noise-sensitive users, or buyers seeking RAID, NAS features, or 10Gbps transfers
- Drive bays:4
- Drive compatibility:2.5-inch and 3.5-inch SATA HDDs and SSDs
- Maximum capacity:Up to 20TB per drive; 80TB total
- Interface:USB 3.0 Type-A and Type-C
- Maximum transfer speed:5Gbps under UASP
- Material:Aluminum alloy
- Cooling and fan noise:2-inch fan; about 40–50 dB
- RAID/NAS support:Not supported
- Compatibility:Windows 7 and above, Mac 9.1 and above, Linux
Our verdict“Choose this CENMATE for uncomplicated four-drive storage if you can accept the audible fan and 5Gbps limit.”
WAVLINK 4-Bay SATA HDD/SSD Enclosure with USB-C and HDMI
The WAVLINK is the most specialized pick here: it combines a four-bay DAS enclosure with HDMI output, so it may suit a desk setup where storage and display connections share one device. Its stated 128TB capacity is the highest among the four-bay options in this batch, and USB-C data transfer reaches 10Gbps, matching the TerraMaster D4-320’s listed link speed. Independent bay switches also give more control when powering drives, while dual temperature-controlled fans activate at 48°C. The extra video feature brings a compatibility catch: HDMI requires a host USB-C port that supports video output, so a standard data-only port will not provide that function. Buyers using 2.5-inch drives also need separate mounting brackets. It is a better fit for a specific desk arrangement than for someone seeking the simplest storage-only box.
Pros:- Supports up to 128TB across four drives
- USB-C data transfer reaches 10Gbps, matching the TerraMaster D4-320
- HDMI output supports up to 4K at 60Hz with a compatible host
- Dual temperature-controlled fans and independent bay switches add cooling and drive control
Cons:- HDMI requires a USB-C host port with video output support
- Mounting brackets for 2.5-inch drives are not included
- Its HDMI feature adds little for buyers who only need direct-attached storage
Best for: Desk users who want four-drive storage and HDMI output from a compatible USB-C host
Not ideal for: Buyers with data-only USB-C ports or 2.5-inch drives who do not want to source mounting brackets
- Drive bays:4
- Supported drives:3.5-inch and 2.5-inch SATA HDDs and SSDs
- Maximum capacity:128TB (4 x 32TB)
- Data transfer rate:Up to 10Gbps
- Interfaces:USB 3.2 Type-C, HDMI
- HDMI output:Up to 4K at 60Hz (DP 1.4)
- Cooling:Dual fans activate at 48°C
- Material:Aluminum
- Dimensions and weight:7.2 x 5 x 6.4 inches; 2.4 pounds
Our verdict“Choose the WAVLINK if you will use its HDMI output with a compatible host and want four high-capacity drive bays.”
CENMATE Dual-Bay Aluminum Hard Drive Enclosure with Cooling Fan
When two bays are enough, this CENMATE offers a smaller-scale way to add SATA storage than the four-bay CENMATE or TerraMaster D4-320. Tool-free installation and hot swapping make it convenient for drive rotation, while daisy-chain expansion lets users connect up to three devices for a stated 120TB total. That expansion path is useful if capacity grows, though it means adding enclosures rather than filling a single multi-bay unit. The USB 3.0 connection tops out at 5Gbps, so it gives up the faster 10Gbps link available on the TerraMaster. Its built-in fan supports cooling but is specified at about 40–50 dB, which may be distracting near a desk. There is no RAID or NAS support, making it a basic direct-attached choice for separate drives.
Pros:- Supports 2.5-inch and 3.5-inch SATA HDDs and SSDs
- Tool-free installation and hot swapping simplify drive changes
- Daisy-chain expansion supports up to 120TB across three devices
- USB-A and USB-C connectivity supports transfer speeds up to 5Gbps
Cons:- Two bays provide less capacity in one enclosure than the four-bay CENMATE
- The built-in fan produces about 40–50 dB of noise
- No RAID or NAS support, and the link is slower than the TerraMaster D4-320
Best for: Desktop users who need two SATA drives now and want the option to expand with daisy-chained enclosures
Not ideal for: Buyers who need four or more bays in one unit, quiet operation, or RAID/NAS functions
- Number of bays:2
- Drive compatibility:2.5-inch and 3.5-inch SATA HDDs and SSDs
- Maximum capacity:20TB per drive
- Interface:USB 3.0, USB-A/USB-C
- Transfer speed:Up to 5Gbps
- Cooling and fan noise:Built-in 2-inch fan; about 40–50 dB
- Installation:Tool-free
- Features:Hot swapping, daisy-chain expansion
- Daisy-chain capacity and compatibility:Up to 120TB across 3 devices; Windows 7 and above, Mac 9.1 and above, Linux
Our verdict“Pick this CENMATE if two bays fit your current needs and you prefer staged expansion over a four-bay enclosure.”
How We Picked
I compared the 15 listed enclosures by the decisions buyers make before adding drives: bay count, stated connection type, RAID support, drive-size compatibility, cooling, and the degree of setup flexibility. I gave weight to practical fit: extra bays matter for a growing archive, RAID choices matter when capacity and data protection must be balanced, and a smaller enclosure can be easier to place when only two drives are needed. Product descriptions do not establish real-world transfer rates, noise levels, or long-term reliability, so I do not treat those as proven advantages.
The ranking favors models with a clear role and a useful combination of capacity, connection, and control. The six-bay TERRAMASTER D6-320 takes the overall spot for expansion; UGREEN’s five-bay model ranks highly for its stated RAID variety; simpler two-bay units suit buyers who value a compact setup over growth. Similar bay counts are separated by documented differences such as RAID modes, USB generation, cooling, or support for mixed drive sizes. A buyer should confirm exact RAID behavior, host compatibility, and supported drive capacities before purchase.
Factors to Consider When Choosing Das Enclosure
Before choosing a DAS enclosure, start with the drives and computer you already own, then decide how much capacity and protection you need. The right bay count and RAID setup can matter more than a headline connection label. These factors help avoid buying extra complexity—or running out of room too soon.
Choose Bay Count Around Your Next Upgrade
Count the drives you plan to install now, then think about whether you are likely to add more during the enclosure’s life. A two-bay model can keep a desktop backup setup compact, but it leaves no room for growth without replacing the enclosure. Four- and five-bay designs provide a middle ground for media libraries and project archives. Six bays, as on the TERRAMASTER D6-320, give the most room among these listed options, though unused bays still take up desk space. Do not buy on bay count alone: confirm which drive sizes and capacities the specific model supports. If your storage needs are uncertain, a few spare bays may be more useful than paying for a feature you will not use.
Treat RAID as a Data-Management Choice
RAID modes can combine drives for capacity, speed, or redundancy, but these goals do not all fit the same configuration. More RAID modes, such as the eight listed for UGREEN’s five-bay enclosure, provide options; they also mean more decisions before setup. RAID is not a substitute for a separate backup, since enclosure failure, accidental deletion, or other events can affect the array. Avoid choosing a mode solely because its name suggests protection: check how it handles a failed drive and whether it reduces usable capacity. If you are new to multi-drive storage, favor a configuration you can explain and maintain. Keep another copy of important files on separate storage.
Match the Whole Connection Path
A fast-sounding port cannot speed up a chain that includes a slower computer port, cable, or drive. Check the enclosure’s exact USB standard and connector, then compare them with the ports on the computer you will use. USB-C describes the connector shape; it does not by itself specify the data rate. Mechanical hard drives may also be the limit during large transfers, so a higher connection ceiling may matter more with SSDs or multiple drives. Use the supplied or a suitably rated cable and avoid relying on adapters without checking their capabilities. For backups and general file access, consistent compatibility can matter more than choosing the highest listed bandwidth.
Check Cooling, Noise, and Placement
Several enclosures in this roundup list cooling fans, which can help move heat away from multiple installed drives. A fan also adds another moving part and may be audible near a desk or in a quiet room. More bays packed together can make airflow and placement more relevant than they are with a two-bay unit. Look for unobstructed intake and exhaust space rather than pushing an enclosure into a closed cabinet. Product listings alone do not settle how loud a fan will sound in your room, so check the design details and return terms if noise is a priority. Think about cable routing and access to drive trays as well as the enclosure’s footprint.
Confirm Drive Fit and RAID Control
Check whether you are installing 3.5-inch desktop drives, 2.5-inch drives, SSDs, or a mix; compatibility varies by enclosure. The ORICO five-bay model in this group explicitly names both 2.5- and 3.5-inch support, while other listings may describe a narrower set. Also find out how RAID is configured: some enclosures may rely on switches or hardware controls, while others may need software or host-side setup. Do not assume that two products with the same number of bays manage drives the same way. Check whether drives are hot-swappable and whether changing a configuration can erase existing data. If you may move the enclosure between computers, verify how its array will be recognized on each system.
Frequently Asked Questions
Should I choose a two-bay enclosure or start with four or more bays?
A two-bay enclosure makes sense when you know that two drives will cover your needs and you want a smaller setup. If your library, footage, or backup set is likely to grow, a four-, five-, or six-bay model can avoid replacing the enclosure later. More bays do not automatically mean better protection; the RAID layout and separate backups still matter. Consider how many drives you will install in the next year or two, not just today. The TERRAMASTER D6-320 is the expansion-minded option here, while the TerraMaster D2-320 is a more focused two-drive choice.
Does a USB-C enclosure guarantee faster transfers than USB 3.0?
No. USB-C identifies the connector, while the data rate depends on the USB specification supported by the enclosure, cable, and computer port. A USB-C enclosure connected through a slower port or adapter may not reach its advertised interface speed. The drives themselves can also limit sustained transfers, especially when using mechanical disks. Match the specifications at both ends of the connection and use a cable rated for the required standard. For everyday backups, compatibility and reliable connection may matter more than the highest theoretical rate.
Will RAID protect my files if an enclosure or drive fails?
Some RAID modes can keep an array available after a drive failure, but the level of protection depends on the mode and number of drives. RAID does not protect against every failure, accidental deletion, theft, or damage to the enclosure itself. Treat it as one part of a storage plan and keep a separate copy of files you cannot replace. Before choosing a mode, confirm how much space it uses and what happens when a drive fails. The UGREEN model’s listed RAID variety gives buyers more configuration choices, but those choices still require a clear backup plan.
Can I mix 2.5-inch and 3.5-inch drives in one enclosure?
Only if the enclosure supports both sizes and the trays or mounting hardware accommodate your specific drives. The ORICO five-bay model in this roundup explicitly lists support for 2.5- and 3.5-inch drives, but that should not be assumed for every model. Mixed drive sizes or capacities can also affect which RAID configurations are available and how much usable space you get. Check the manufacturer’s compatibility details before buying, especially if you plan to reuse existing drives. For important data, confirm the array behavior before moving drives into a new enclosure.
Is an enclosure with a cooling fan a poor choice for a quiet office?
A fan can help move heat from several drives, but it may be audible, and the listing alone does not establish its noise level. A multi-bay enclosure with active cooling may suit long transfers or drives running for extended periods better than a passively cooled unit, depending on its design and placement. If the enclosure will sit within arm’s reach, look for fan controls or noise information from the manufacturer. Leave space around vents, since cramped placement can make cooling less effective. For a quiet desk setup, compare fan-equipped CENMATE models with the enclosure’s location and likely workload before deciding.
Conclusion
For most buyers who expect their storage collection to grow, I recommend the TERRAMASTER D6-320 as the best overall because its six bays leave more room to expand. The ORICO 5-Bay enclosure for 2.5- and 3.5-inch drives is my best value-style fit for buyers who need broad drive-size compatibility without prioritizing the most bays. For a more feature-focused premium pick, consider the UGREEN 5-Bay USB-C model if its eight RAID modes match a setup you understand and will maintain. Beginners with a straightforward two-drive plan should look at the TerraMaster D2-320; people who want active cooling in a compact dual-bay format can compare the CENMATE dual-bay options. Choose a four-bay model such as the TerraMaster D4-320 when two bays feel restrictive but six would be excess, and verify drive fit, host connection, and RAID behavior before committing.
