Among these encrypted external hard drives, I’d put the Apricorn Aegis Fortress L3 2TB first for buyers who want dedicated hardware encryption and more room than the Padlock models. The Apricorn Aegis Padlock 1TB is a more compact-capacity choice, while the OSCOO 1TB touchscreen SSD stands out for buyers who prefer an on-device touch interface. The WD My Passport drives offer capacities up to 5TB, but the listed models do not specify hardware encryption, so they are not direct substitutes for the security-focused picks. Choosing between them means weighing encryption clarity and access controls against capacity, interface, and everyday convenience. Read on for the full comparison and guidance on matching a drive to your security needs.

Key Takeaways

  • The Apricorn models are the clearest security-focused choices: the Aegis Fortress L3 pairs hardware encryption with 2TB capacity, while the Padlock line offers keypad access at 500GB and 1TB.
  • Capacity alone does not establish encryption: WD My Passport models are listed at 2TB, 4TB, and 5TB, but the product details provided do not identify hardware encryption.
  • The OSCOO’s touchscreen sets it apart: it offers a distinct on-device access approach in a 1TB SSD, rather than the keypad design used by Apricorn’s Padlock drives.
  • There is a clear capacity-versus-security tradeoff in this lineup: the largest listed drives are the WD models, while the options with specified hardware encryption offer less capacity.
  • Buy by security requirement, not by the word “external” or storage size: confirm the exact encryption method, authentication process, and recovery plan before storing sensitive files.

More Details on Our Top Picks

  1. Apricorn Aegis Padlock 500GB USB 3.0 Encrypted Portable Hard Drive

    Apricorn Aegis Padlock 500GB USB 3.0 Encrypted Portable Hard Drive

    Best for Minimal Software-Free Security

    View Latest Price

    I’d choose the 500GB Aegis Padlock when keeping access control on the drive itself matters more than carrying a large library. Its 256-bit AES-XTS hardware encryption works in real time, and the keypad lets you unlock it without installing software—a useful difference from the WD My Passport 2TB, which relies on downloadable software for its management and backup features. Epoxy-protected circuitry and a reset feature add layers of protection beyond the PIN, though they do not make this a high-capacity or fast-transfer choice.

    The main compromise is straightforward: 500GB fills quickly beside the 1TB Aegis Padlock or 2TB Aegis Fortress L3. PIN entry also adds a step each time you access the drive. I’d pick it for focused storage of sensitive files, not as a roomy all-purpose backup drive.

    Pros:
    • 256-bit AES-XTS hardware encryption operates in real time
    • Keypad access does not require software installation
    • Epoxy-protected circuitry adds a physical security layer
    • USB 3.0 supports newer ports and remains backward compatible with USB 2.0 and 1.1
    Cons:
    • 500GB capacity limits its usefulness for large backups
    • PIN entry adds a step whenever the drive is unlocked
    • The listed 5400 rpm mechanical drive is not a solid-state option

    Best for: People who need a modest amount of sensitive data protected by onboard hardware encryption and want to avoid installing drive software.

    Not ideal for: Photographers, video editors, or anyone keeping large archives, since 500GB offers much less space than the other Apricorn drives here.

    • Storage capacity:500 GB
    • Encryption:256-bit AES-XTS hardware encryption
    • Interface:USB 3.0; backward compatible with USB 2.0 and 1.1
    • Form factor:2.5 inches
    • Rotational speed:5400 rpm
    • Enclosure material:Metal
    • Security features:Keypad, epoxy-protected circuitry, and drive reset feature
    Our verdict
    “Choose this Aegis Padlock for PIN-controlled, software-free protection of a smaller file collection, but pick a higher-capacity model for broader backups.”
  2. Apricorn Aegis Fortress L3 2TB Hardware-Encrypted Portable Drive

    Apricorn Aegis Fortress L3 2TB Hardware-Encrypted Portable Drive

    Best for Validated High-Security Requirements

    View Latest Price

    The Aegis Fortress L3 is the most security-focused pick here: it combines 256-bit AES-XTS hardware encryption with FIPS 140-2 Level 3 validation, an onboard keypad, forced PIN enrollment, and brute-force defense. Those controls make it a stronger fit for managed or regulated environments than the simpler Apricorn Aegis Padlock 1TB, which also offers hardware encryption and keypad access but does not list the same validation. Read-only modes add flexibility when users should retrieve files without changing them.

    That extra control comes with practical costs. At 1.1 pounds, it is heavier than a compact everyday drive, and it needs a powered USB port. Mass configuration also requires a separately sold Aegis Configurator. I’d favor it when policy-driven security matters more than light carry or simple fleet setup.

    Pros:
    • FIPS 140-2 Level 3 validated security
    • Forced PIN enrollment, keypad access, and brute-force defense
    • Read-only modes help limit changes to stored files
    • Works without software or drivers on PC, Mac, Linux, and mass storage-compliant systems
    Cons:
    • Weighs 1.1 pounds, making it less convenient for frequent carry
    • Requires a powered USB port
    • Aegis Configurator for mass configuration is sold separately

    Best for: Organizations and professionals who need a portable encrypted drive with stated FIPS 140-2 Level 3 validation and onboard access controls.

    Not ideal for: Travelers prioritizing a light, uncomplicated drive, or teams that need mass configuration without purchasing separate software.

    • Storage capacity:2TB
    • Encryption:256-bit AES-XTS hardware encryption
    • Security validation:FIPS 140-2 Level 3
    • Interface:USB 3.0
    • Enclosure:Aircraft-grade 6061 aluminum alloy
    • Weight:1.1 pounds
    • Additional security features:Onboard keypad, forced PIN enrollment, read-only modes, and brute-force defense
    • Compatibility:PC, Mac, Linux, and mass storage-compliant systems
    Our verdict
    “Pick the Fortress L3 when validated security controls outweigh weight and setup costs, rather than choosing a simpler Aegis Padlock for basic protected storage.”
  3. WD My Passport 2TB Portable External Hard Drive, Black

    WD My Passport 2TB Portable External Hard Drive, Black

    Best for Everyday Backup Convenience

    View Latest Price

    The WD My Passport 2TB suits buyers who want encrypted storage as part of an everyday backup routine rather than a keypad-first security device. It pairs hardware encryption and password protection with downloadable backup and device management software, giving it a more guided setup than the Apricorn Aegis Padlock 500GB. Its 2TB capacity also leaves more room for a mixed collection of documents, photos, and media than that smaller Apricorn.

    The tradeoff is that its convenience depends on software: you must download and install it, and account registration may be required for some uses. By contrast, the Aegis Padlock works without software and keeps PIN entry on the drive. WD’s model is therefore a better match for routine personal backups, but less appealing to people who want a standalone, hardware-keypad workflow or the higher-capacity WD My Passport 4TB.

    Pros:
    • 2TB capacity for everyday files and backups
    • Hardware encryption paired with password protection
    • Backup and device management software is available
    • Compact 2.5-inch portable drive with a three-year limited warranty
    Cons:
    • Backup and management software must be downloaded and installed
    • Some software use may require account registration
    • Provides no listed onboard keypad like the Apricorn encrypted drives

    Best for: Home and personal-computer users who want 2TB of portable storage with password protection and downloadable tools for managing backups.

    Not ideal for: Buyers who avoid software downloads or account registration, or who need keypad-based access controls and software-free operation.

    • Storage capacity:2 TB
    • Drive type:Mechanical hard disk
    • Form factor:2.5 inches
    • Connectivity:USB 2.0 and USB 3.0
    • Encryption:Hardware encryption and password protection
    • Included software:Downloadable device management and backup software
    • Warranty:3-year limited warranty
    Our verdict
    “Choose the WD My Passport 2TB for software-assisted personal backups with encryption, but select an Apricorn model if you want access controls on the drive itself.”
  4. Apricorn Aegis Padlock 1TB USB 3.0 Hardware-Encrypted Portable External Hard Drive

    Apricorn Aegis Padlock 1TB USB 3.0 Hardware-Encrypted Portable External Hard Drive

    Best Software-Free Mid-Capacity Pick

    View Latest Price

    The 1TB Aegis Padlock offers a useful middle ground for buyers who want Apricorn’s keypad-based, software-free approach without settling for the 500GB model’s tighter capacity. It encrypts data in real time with 256-bit AES-XTS hardware encryption, works without administrator rights, and supports Windows, Mac, and Linux. Compared with the WD My Passport 2TB, it avoids downloadable backup software and account-related setup, while its epoxy-sealed circuitry and brute-force self-destruct feature emphasize access protection.

    Capacity remains the tradeoff: the WD provides twice as much space, and the Aegis Fortress L3 adds stated FIPS 140-2 Level 3 validation for buyers with stricter requirements. The keypad also means unlocking takes an extra step. I’d choose this model for a moderate set of sensitive files, not for a large media archive or a compliance-driven deployment.

    Pros:
    • Real-time 256-bit AES-XTS hardware encryption
    • Operates without software installation or administrator rights
    • Compatible with Windows, Mac, and Linux
    • Epoxy-sealed circuitry and brute-force self-destruct feature add protective layers
    Cons:
    • 1TB capacity is smaller than the 2TB WD My Passport and Aegis Fortress L3
    • Keypad PIN entry adds friction to repeated access
    • USB 3.0 performance depends on the connected port

    Best for: People with a moderate-sized collection of sensitive files who need encrypted storage across Windows, Mac, or Linux without installing software.

    Not ideal for: Users with large backup libraries or formal security validation requirements, who may be better served by the WD My Passport 2TB or Aegis Fortress L3.

    • Storage capacity:1TB (1024GB)
    • Encryption:256-bit AES-XTS hardware encryption
    • Interface:USB 3.0; backward compatible with USB 2.0 and 1.1
    • Form factor:2.5 inches
    • Rotational speed:5400 rpm
    • Compatibility:Windows, Mac, and Linux
    • Security features:Epoxy-sealed circuitry, wear-resistant keypad, and brute-force self-destruct feature
    • Enclosure material:Aluminum/Glass
    Our verdict
    “Choose the 1TB Aegis Padlock for software-free PIN access and more room than the 500GB model, but look elsewhere for larger archives or validated security.”
  5. WD My Passport 4TB Portable External Hard Drive, Black

    WD My Passport 4TB Portable External Hard Drive, Black

    Best for High-Capacity Encrypted Backups

    View Latest Price

    The WD My Passport 4TB is the capacity choice for buyers who want encrypted portable storage for a broad backup library. Its password protection and hardware encryption provide a security layer, while included backup and device management software—with ransomware defense—makes it more oriented toward routine backup workflows than the keypad-equipped Apricorn Aegis Padlock 1TB. Four terabytes also gives it substantially more room than the 2TB WD My Passport for large photo, video, and document collections.

    That storage comes without the Apricorn drives’ listed onboard keypad and software-free setup, so buyers should check whether WD’s software-led approach suits their privacy and maintenance preferences. The product details do not specify a transfer rate or a keypad-based unlock method. I’d pick it for capacity-led backups, but choose the Fortress L3 when validated security controls are the priority.

    Pros:
    • 4TB capacity for larger backup collections
    • Hardware encryption paired with password protection
    • Backup and device management software includes ransomware defense
    • Three-year limited warranty
    Cons:
    • Does not list an onboard keypad like the Apricorn Aegis Padlock models
    • Backup and device management features rely on included software
    • No transfer speed is specified in the provided product details

    Best for: People maintaining large personal or work backups who want 4TB of portable storage with hardware encryption and backup tools.

    Not ideal for: Buyers who need FIPS-validated security or a drive that can be unlocked using an onboard keypad without relying on management software.

    • Storage capacity:4TB
    • Drive type:Portable external hard drive
    • Connectivity:USB 3.1 / USB 3.0
    • Security:Password protection and hardware encryption
    • Included software:Device management and backup software with ransomware defense
    • Color:Black
    • Warranty:3-year limited warranty
    • Model:WDBPKJ0040BBK-WESN
    Our verdict
    “Choose the WD My Passport 4TB when backup capacity and software tools matter more than keypad access or formal security validation.”
  6. WD My Passport 5TB Portable External Hard Drive, Black

    WD My Passport 5TB Portable External Hard Drive, Black

    Best for High-Capacity Backups

    View Latest Price

    The WD My Passport 5TB is the capacity-focused choice here: it holds more than the 2TB and 4TB WD My Passport options while keeping the same slim portable-drive approach. That extra room suits large photo libraries and recurring computer backups, and its password protection and hardware encryption add a security layer for files carried away from home. WD backup software with ransomware protection is another practical advantage for routine file copies. The tradeoff is that this is a conventional hard drive, not a fast solid-state drive like the OSCOO 1TB Touchscreen Encrypted External SSD, so it is better for roomy archives than speed-sensitive work. Mac users should also plan to reformat it, and the supplied details do not specify a particular encryption standard or authentication method.

    Pros:
    • 5TB capacity provides room for large backups and file collections.
    • Password protection and hardware encryption help protect stored files.
    • Backup software includes ransomware protection.
    • Slim 2.5-inch body weighs 7.4 ounces for portable storage.
    Cons:
    • Mac compatibility requires reformatting.
    • Hard-drive storage is less suited to speed-intensive workflows than the OSCOO SSD.
    • The provided specifications do not state an encryption standard or authentication method.

    Best for: People who want a portable, encrypted drive for large photo libraries, documents, and regular computer backups.

    Not ideal for: Mac users who want a drive ready to use without reformatting, or creators who need SSD-class transfer speeds for active projects.

    • Storage capacity:5 TB
    • Interface:USB 2.0/3.0
    • Form factor:2.5 inches
    • Security:Password protection and hardware encryption
    • Backup software:Includes backup software with ransomware protection
    • Weight:7.4 ounces
    • Dimensions:4.22 x 2.95 x 0.75 inches
    • Warranty:3-year limited warranty
    Our verdict
    “Choose the WD My Passport 5TB if encrypted capacity for backups matters more than SSD speed or out-of-box Mac setup.”
  7. OSCOO 1TB Touchscreen Encrypted External SSD

    OSCOO 1TB Touchscreen Encrypted External SSD

    Best for Fast, Status-Visible Storage

    View Latest Price

    The OSCOO 1TB takes a different route from the WD My Passport drives: it pairs hardware encryption and password protection with an SSD rated up to 2,000 MB/s read, rather than prioritizing high-capacity hard-drive storage. That makes it the more suitable fit for moving active project files or recording ProRes video directly from compatible Apple devices. Its touchscreen reports speed, temperature, and available capacity, giving mobile creators a quick way to check drive status. The zinc alloy housing, magnetic design, and broad USB-C compatibility add flexibility across supported devices. Those features come with a capacity tradeoff: 1TB is far less room than the WD My Passport 5TB. The listing also gives conflicting interface information, so I would verify the connection details before buying, and ProRes recording requires compatible Apple hardware.

    Pros:
    • Rated read and write speeds of up to 2,000 MB/s and 1,800 MB/s.
    • Hardware encryption and password protection secure stored files.
    • Touchscreen shows transfer speed, temperature, and available capacity.
    • Zinc alloy housing, magnetic design, and compatibility across many USB-C device types.
    Cons:
    • 1TB capacity is substantially smaller than the WD My Passport 5TB.
    • The product details conflict: they list USB 3.2 Gen 2×2 and also describe a USB 2.0/3.0 hard-drive interface.
    • Direct ProRes recording is limited to compatible Apple devices.

    Best for: Mobile creators and USB-C device owners who need encrypted, fast storage and want visible drive-status information.

    Not ideal for: Buyers building large backup archives, or anyone who needs confirmed interface specifications or ProRes recording on non-compatible Apple devices.

    • Storage capacity:1 TB
    • Interface:USB 3.2 Gen 2×2 listed; product details also conflict with a USB 2.0/3.0 interface listing
    • Read speed:Up to 2,000 MB/s
    • Write speed:Up to 1,800 MB/s
    • Security:Hardware encryption and password protection
    • Display:Touchscreen with real-time drive monitoring
    • Housing:Zinc alloy
    • Weight:52 g
    • Compatibility:Windows, Mac, iPhone, iPad, Android devices, cameras, and gaming consoles
    Our verdict
    “Pick the OSCOO if fast encrypted storage and on-drive status matter more than the roomy capacity of the WD My Passport 5TB.”

How We Picked

I ranked these drives by how clearly their listed features support the roundup’s central need: storing files with a defined encryption and access-control approach. Hardware encryption and a directly described authentication method count more than capacity alone, so the Apricorn Fortress L3 and Padlock models sit ahead of WD My Passport models whose supplied product names do not specify encryption. I also weighed usable capacity, the practical differences between a keypad and touchscreen, and whether the product’s role is clear for a particular buyer.

The order reflects how well each option fits secure storage, not a claim that every model has equivalent protection. The Fortress L3 leads for its stated hardware encryption and 2TB capacity; the 1TB Padlock follows as a more accessible-capacity keypad option, while the 500GB version suits smaller archives. The OSCOO offers an SSD and touchscreen distinction, but its listing gives less detail about encryption than the Apricorn products. WD’s higher capacities may suit general storage needs, but buyers seeking encrypted storage should verify the exact model’s protection features before treating those drives as security-focused alternatives.

Factors to Consider When Choosing Encrypted External Hard Drives

Before choosing among these encrypted external hard drives, I’d separate three questions: what protection the drive actually provides, how much storage your files need, and how you will regain access if authentication fails. These checks can prevent a high-capacity purchase that does not meet your security needs—or a secure drive that is awkward to use day to day.

Confirm What “Encrypted” Means for the Exact Model

Product names and broad category labels do not always tell you whether encryption is built into the drive, enabled through software, or absent from that particular model. Look for explicit documentation of the encryption method and where keys are handled, then check that the information applies to the exact capacity and model number you plan to buy. A drive that relies on software may behave differently across operating systems or computers than one with onboard encryption. Do not assume that a brand’s security-focused product line makes every portable drive from that brand encrypted. If the listing is unclear, consult the manufacturer’s product documentation before storing sensitive material.

Choose Authentication You Can Use Reliably

Keypads and touchscreens put authentication on the drive itself, which can reduce dependence on software installed on a host computer. They also ask you to remember a PIN and use the device interface each time you unlock it. Consider where you will access the drive: a keypad may be easier to operate in varied lighting, while a touchscreen may feel more familiar but can add another point of interaction. Check how the device handles failed attempts, PIN changes, and recovery, rather than judging security by the interface alone. A strong access method is only useful if you can operate it consistently without creating unsafe workarounds.

Size Capacity Around Real Files and Backup Growth

Estimate your current files, then allow room for new versions and future backups rather than buying only for today’s collection. Photos, video, and system images can consume storage quickly, but a larger drive is not automatically the better secure-storage purchase if its encryption features are unconfirmed. Think about whether the drive will hold one working archive or a separate copy of data already stored elsewhere. Keeping a separate backup matters because encryption protects confidentiality, not against loss, damage, or accidental deletion. If you need both high capacity and defined encryption, verify that the exact model offers both before choosing.

Treat Recovery and Backups as Part of Security

Encryption can make forgotten credentials a serious access problem, so learn the recovery process before putting important files on a drive. Check whether recovery depends on a backup PIN, an administrator process, or another method, and store any recovery information separately from the drive. Do not keep your only copy of valuable files on a device that can be locked, lost, or damaged. A second backup should be protected too, especially if it contains the same sensitive material. This planning is easy to postpone, but it can matter more than a small difference in capacity or interface.

Match Drive Type to Portability and Workload

Portable hard drives and SSDs can differ in speed, capacity, and how they suit frequent travel or repeated file transfers. A touchscreen SSD such as the OSCOO occupies a different role from the keypad-equipped Apricorn hard drives, but interface style alone does not establish encryption strength or durability. Check the connection type and compatibility with your computer, phone, or other host before buying. If you move large files often, transfer performance may matter; if the drive stays in a drawer as an archive, capacity and recovery planning may matter more. Avoid paying for speed or an interface you will rarely use when your main need is protected storage.

Check Compatibility Before You Depend on a Drive

Encryption features, unlocking software, and file-system formatting can affect whether a drive works smoothly across Windows, macOS, and other devices. Verify support for the operating systems you actually use, including any requirements for unlocking or administering the drive. A drive that opens on one computer may need setup or reformatting before another system can use it, and reformatting can erase stored data. If you plan to share access with a team or switch between work and personal devices, check those workflows before purchase. Compatibility should be tested with noncritical files before the drive becomes part of your backup routine.

Frequently Asked Questions

Are the WD My Passport models in this roundup encrypted?

The listed WD My Passport product names identify portable storage and capacity, but the supplied details do not specify hardware encryption. I would not treat a model as an encrypted drive based on its brand or capacity alone. Check the exact model’s current documentation for encryption and access-control features, and distinguish password protection from encryption if both are discussed. If hardware encryption is a firm requirement, the Apricorn models in this roundup have more explicit security positioning in their listed names.

Should I choose the Apricorn Aegis Fortress L3 or a Padlock model?

The Fortress L3 is the stronger fit if you want a stated hardware-encrypted Apricorn drive with 2TB of space. The Padlock models make sense when you prefer their keypad access and need either 1TB or a smaller 500GB capacity. Compare the specific model documentation for authentication, recovery, and compatibility before deciding; capacity and product family names do not answer every security question. Choose based on the files you need to store and the access method you can use reliably.

Is a touchscreen encrypted SSD a better choice than a keypad hard drive?

Not automatically: the touchscreen and keypad describe different ways to interact with a device, not a complete measure of protection. The OSCOO 1TB SSD may appeal if you favor an on-device touch interface and SSD form, while the Apricorn Padlock models offer keypad access. Check the exact encryption specifications, recovery process, connection compatibility, and transfer needs for each model. Pick the interface that suits your routine only after confirming it meets your security requirements.

Can I use an encrypted external drive for my only backup?

I would not rely on a single external drive as the only copy of important files. Encryption can help protect data from unauthorized access, but it does not prevent hardware failure, loss, damage, or accidental deletion. Keep another copy in a separate location and protect that copy appropriately as well. Before trusting either backup, confirm you can unlock it and restore files on the computer or system you expect to use.

What should I do if I forget the drive’s PIN or password?

Recovery options vary by model, so read the manufacturer’s instructions before setting up the drive and before saving important data to it. Some devices may offer a recovery credential or administrative process, while others may not provide a way to regain access to encrypted contents without the correct credentials. Store recovery information separately from the drive and avoid relying on memory alone for a credential you use infrequently. Keep another verified copy of your files so a forgotten PIN does not become a permanent data-loss event.

Conclusion

For the best overall fit in this roundup, I’d choose the Apricorn Aegis Fortress L3 2TB: it combines stated hardware encryption with more capacity than the Padlock options. The Apricorn Aegis Padlock 1TB is my best value-style pick for buyers who want keypad access without needing 2TB, while the 500GB Padlock suits a smaller secure archive. For a premium-leaning choice with a different interface, the OSCOO 1TB Touchscreen Encrypted SSD is the distinct option, though I’d verify its detailed encryption and recovery specifications first. Beginners who want a clearly described security-focused direction should start with an Apricorn model and review its setup and recovery instructions before loading files. If your priority is maximum listed capacity rather than specified encryption, the WD My Passport 4TB or 5TB may suit general storage, but confirm the exact model’s encryption features before using it for sensitive data.
