Among these encrypted external hard drives, I’d put the Apricorn Aegis Fortress L3 2TB first for buyers who want a dedicated hardware-encrypted drive and more capacity than the Padlock models. The Apricorn Aegis Padlock 1TB is a more straightforward security-focused choice, while the OSCOO 1TB Touchscreen Encrypted External SSD suits buyers who prefer an SSD form factor and a screen-based interface. The main tradeoffs are security controls versus everyday convenience, and dedicated encryption versus the larger capacities available from WD’s My Passport drives. The My Passport models may fit general storage needs, but don’t assume their inclusion makes them equivalent to products explicitly marketed with hardware encryption. Read on for the full comparison and guidance on choosing the right kind of protection.

Key Takeaways

  • The Apricorn Fortress L3 2TB leads this security-focused group because it combines dedicated hardware encryption with the largest capacity among the explicitly encrypted Apricorn and OSCOO options listed.
  • The Apricorn Padlock 1TB is a more balanced portable-drive pick than the 500GB Padlock when storage headroom matters, while both make more sense for security-led use than the WD My Passport models.
  • Capacity is not the same as encryption. The WD My Passport 2TB, 4TB, and 5TB drives offer more capacity choices, but the listed product names do not specify dedicated hardware encryption.
  • The OSCOO stands apart by using an SSD and touchscreen interface, a different format from the spinning portable hard drives in the lineup; buyers should weigh that interface and form factor against their capacity needs.
  • The roundup’s clearest tradeoff is dedicated security versus general-purpose storage. Buyers handling sensitive files should prioritize documented encryption and access controls, while those needing bulk space should verify protection details before choosing a standard portable drive.

  1. 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 for Software-Free Security

    View Latest Price

    The Apricorn Aegis Padlock 1TB suits buyers who want hardware encryption without installing software or relying on computer administrator access. Its keypad grants access directly on the drive, while 256-bit AES-XTS encryption, epoxy-sealed circuitry, and brute-force self-destruct protection add layers beyond a standard password-protected portable disk. Compared with the WD My Passport 2TB, it gives security more prominence but offers half the capacity and skips the WD’s downloadable backup and management tools. The USB 3.0 connection also works with older USB 2.0 and 1.1 ports, though those connections can limit transfer speed. The keypad adds a step each time you unlock it, and the 1TB capacity may be restrictive for large media libraries. I’d choose it for protected work files, not as the lineup’s highest-capacity backup drive.

    Pros:
    • Real-time 256-bit AES-XTS hardware encryption
    • Works without software installation or administrator rights
    • USB 3.0 connection is backward compatible with USB 2.0 and 1.1
    • Epoxy-sealed circuitry and brute-force self-destruct protection
    Cons:
    • PIN keypad adds an access step compared with software-managed drives
    • 1TB capacity is below the 2TB and 5TB WD My Passport options
    • Transfer speeds can be limited by older USB ports

    Best for: People carrying sensitive work files between Windows, Mac, or Linux computers where software installation or administrator access is unavailable.

    Not ideal for: Photographers and video creators with large archives who need more than 1TB or want included backup software.

    • 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 this Padlock if you want keypad-controlled hardware encryption without software, and skip it if capacity matters more than access security.”
  2. Apricorn Aegis Fortress L3 2TB Hardware-Encrypted Portable Drive

    Apricorn Aegis Fortress L3 2TB Hardware-Encrypted Portable Drive

    Best for High-Assurance Security

    View Latest Price

    The Apricorn Aegis Fortress L3 is the security-led choice here: its FIPS 140-2 Level 3 validation, onboard keypad, forced PIN enrollment, and read-only modes make it a stronger fit for controlled environments than the WD My Passport drives. Hardware encryption runs on the drive, so use does not depend on software or drivers; that helps when moving between PC, Mac, Linux, and mass-storage-compliant systems. Its aircraft-grade aluminum enclosure and brute-force defense add physical and access safeguards, while 2TB gives it more room than the 1TB Aegis Padlock. The tradeoff is a heavier 1.1-pound unit that requires a powered USB port, and mass configuration calls for a separately sold Aegis Configurator. This is a more specialized security tool than a simple backup disk, and buyers who do not need its validation may prefer a less demanding setup.

    Pros:
    • FIPS 140-2 Level 3 security validation
    • 256-bit AES-XTS hardware encryption with no software or drivers required
    • Forced PIN enrollment, read-only modes, and brute-force defense
    • Rugged aircraft-grade 6061 aluminum enclosure
    Cons:
    • At 1.1 pounds, it is heavier than the compact WD My Passport drives
    • Requires a powered USB port
    • Mass configuration requires a separately sold Aegis Configurator

    Best for: Organizations and professionals handling sensitive files who need validated hardware encryption, PIN controls, and read-only access options across multiple operating systems.

    Not ideal for: Casual home users seeking a lightweight, plug-and-play backup drive without keypad procedures or specialized configuration needs.

    • Storage capacity:2TB
    • Encryption:256-bit AES-XTS hardware encryption
    • Security validation:FIPS 140-2 Level 3
    • Interface:USB 3.0
    • Enclosure material:Aircraft-grade 6061 aluminum alloy
    • Form factor:2.5 inches
    • Weight:1.1 pounds
    • Compatibility:PC, Mac, Linux, and mass-storage-compliant systems
    Our verdict
    “Pick the Fortress L3 for validated security controls and a rugged build, but choose a WD My Passport for simpler everyday backups.”
  3. WD My Passport 2TB Portable External Hard Drive, Black

    WD My Passport 2TB Portable External Hard Drive, Black

    Best for Everyday Backups

    View Latest Price

    The WD My Passport 2TB makes the most sense for buyers who want a conventional portable backup drive with password protection and hardware encryption, plus downloadable backup and device-management software. Compared with the keypad-equipped Apricorn Aegis Padlock, the WD offers a more familiar software-based setup and twice its capacity, but it does not list the same keypad, epoxy-sealed circuitry, or brute-force self-destruct safeguards. Its compact 2.5-inch mechanical drive is suited to carrying documents, photos, and media, while USB 2.0 and 3.0 connectivity supports older and newer ports. The tradeoff is that the software must be downloaded and installed, and using it may require account registration—less convenient on locked-down computers. I’d choose this for routine personal backups, not for buyers who need independent on-drive PIN access or validated security controls.

    Pros:
    • 2TB capacity for photos, videos, music, and documents
    • Password protection and hardware encryption
    • Downloadable backup and device-management software
    • USB 2.0 and USB 3.0 connectivity
    Cons:
    • Backup and management software must be downloaded and installed
    • Software use may require account registration
    • Does not list the keypad and physical security features found on the Apricorn Aegis Padlock

    Best for: Home and personal users who want 2TB for regular file backups and are comfortable installing WD’s downloadable software.

    Not ideal for: People using restricted work computers or seeking keypad-based access controls, tamper-resistant circuitry, or FIPS-validated security.

    • Storage capacity:2TB
    • Drive type:Mechanical hard disk
    • Form factor:2.5 inches
    • Connectivity:USB 2.0 and USB 3.0
    • Encryption:Hardware encryption
    • Included software:Downloadable device-management and backup software
    • Model:WDBYVG0020BBK-WESN
    • Warranty:3-year limited warranty
    Our verdict
    “Choose the My Passport 2TB for software-assisted everyday backups, but opt for an Apricorn model if keypad-based access security is your priority.”
  4. 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

    With 5TB in a slim 2.5-inch design, this WD My Passport is the capacity pick for buyers who want to keep a large library on one portable encrypted drive. It pairs password protection and hardware encryption with backup software that includes ransomware protection, giving it a broader backup role than the 1TB Apricorn Aegis Padlock. That capacity advantage comes with a different security approach: unlike the Padlock’s onboard keypad and brute-force defense, the WD listing specifies password protection but no physical access controls. The drive connects over USB 2.0 or 3.0 and weighs 7.4 ounces, so it remains portable despite its larger storage pool. Mac users should note the supplied configuration requires reformatting for Mac compatibility, which can complicate a mixed-platform workflow. This is best for bulky backups, not buyers prioritizing hardware-level keypad controls.

    Pros:
    • 5TB capacity exceeds the 1TB and 2TB options in this batch
    • Slim 2.5-inch design weighs 7.4 ounces
    • Password protection and hardware encryption
    • Backup software includes ransomware protection
    Cons:
    • Requires reformatting for Mac compatibility
    • Does not list the keypad access controls found on the Apricorn Aegis Padlock
    • Its large capacity is less useful to buyers with modest backup needs

    Best for: People backing up large photo, video, or document collections who want several terabytes in a portable drive with encryption and backup software.

    Not ideal for: Mac users who need immediate out-of-box compatibility, or security-focused buyers who want an onboard keypad and physical tamper protections.

    • Storage capacity:5TB
    • Interface:USB 2.0/3.0
    • Form factor:2.5 inches
    • Weight:7.4 ounces
    • Dimensions:4.22 x 2.95 x 0.75 inches
    • Security:Password protection and hardware encryption
    • Backup software:Includes backup software with ransomware protection
    • Warranty:3-year limited warranty
    Our verdict
    “Choose this My Passport when you need substantial portable storage with encryption, but favor an Apricorn drive for keypad-led security.”
  5. Apricorn Aegis Padlock 500GB USB 3.0 Encrypted Portable Hard Drive

    Apricorn Aegis Padlock 500GB USB 3.0 Encrypted Portable Hard Drive

    Best Compact-Capacity Security Pick

    View Latest Price

    The Apricorn Aegis Padlock 500GB is a fit for buyers who want the same basic keypad-driven security approach as the 1TB Padlock in a smaller-capacity drive. Its 256-bit AES-XTS hardware encryption works in real time, while epoxy-protected circuitry and a reset feature add protection without requiring software installation. That makes it more suitable for restricted computers than the WD My Passport 2TB, which relies on downloadable software for its backup and management tools. The Padlock connects over USB 3.0 and supports USB 2.0 and 1.1, though older ports can hold back transfers. The main compromise is clear: 500GB is far less room than either WD model or the 1TB Padlock, and the PIN keypad adds a step to access. Choose it for a focused set of sensitive files, not as a roomy all-purpose backup disk.

    Pros:
    • Real-time 256-bit AES-XTS hardware encryption
    • No software installation required
    • USB 3.0 with backward compatibility for USB 2.0 and 1.1
    • Epoxy-protected circuitry and a drive reset feature
    Cons:
    • 500GB capacity is substantially smaller than the 1TB Padlock and WD options
    • PIN entry is required to access the drive
    • USB 2.0 or 1.1 connections can limit transfer speeds

    Best for: People who carry a limited set of sensitive files and need keypad-based hardware encryption on computers where installing software is not practical.

    Not ideal for: Users maintaining large media collections or full-system backups, since its 500GB capacity is the smallest in this batch.

    • Storage capacity:500GB
    • 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
    • Compatible devices:Desktop
    • Compatible game console:Sony PlayStation 4
    Our verdict
    “Choose this Padlock for software-free protection of a smaller file set, or move to the 1TB Padlock if you need more room.”
  6. WD My Passport 4TB Portable External Hard Drive, Black

    WD My Passport 4TB Portable External Hard Drive, Black

    Best High-Capacity Portable Pick

    View Latest Price

    I’d choose the WD My Passport 4TB when carrying a large library matters more than SSD-class speed. Its slim portable design holds substantially more data than the 1TB OSCOO touchscreen SSD, making it a better fit for backups, project archives, and media collections that travel. Password protection and hardware encryption add a security layer, while included backup and device management software with ransomware defense can help users keep files organized and protected. The tradeoff is that this is a traditional external hard drive, not a fast SSD: it is less suited to demanding, speed-sensitive workflows. Its security and backup tools are useful, but buyers seeking a drive built around a dedicated touchscreen or USB-C device compatibility may prefer the OSCOO. The 3-year limited warranty adds practical reassurance for a frequently carried drive.

    Pros:
    • 4TB capacity suits large backups and media libraries
    • Password protection and hardware encryption provide security features for stored files
    • Included backup and device management software adds ransomware defense
    • Slim, portable design and a 3-year limited warranty
    Cons:
    • Traditional hard-drive storage is less suited to speed-intensive workflows than an SSD
    • USB 3.1 / USB 3.0 compatibility may not match USB-C-first setups without the right connection
    • The listed features do not include a touchscreen for checking drive status

    Best for: Traveling photographers, students, and professionals who need several terabytes for backups or media files alongside password protection and hardware encryption.

    Not ideal for: Buyers moving large video projects at SSD speeds or seeking the OSCOO’s touchscreen status display and broad USB-C device support.

    • Capacity:4TB
    • Drive type:Portable external hard drive
    • Security:Password protection and hardware encryption
    • Connection compatibility:USB 3.1 / USB 3.0
    • 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 if you want encrypted, portable storage with ample room for backups and can accept hard-drive speeds rather than SSD performance.”
  7. OSCOO 1TB Touchscreen Encrypted External SSD

    OSCOO 1TB Touchscreen Encrypted External SSD

    Best for Fast USB-C Workflows

    View Latest Price

    The OSCOO 1TB touchscreen SSD is the speed-focused choice here: its listed read and write rates reach 2,000MB/s and 1,800MB/s, respectively, while the display shows transfer speed, temperature, and remaining capacity. That live feedback and hardware encryption give it a different appeal from the capacity-first WD My Passport 4TB, which offers four times the storage and backup software but is a traditional hard drive. The OSCOO’s zinc alloy housing, 52g weight, and magnetic design suit a compact kit for compatible USB-C devices, including some Apple devices recording ProRes directly to the drive. Buyers should check compatibility before relying on that workflow: ProRes recording requires compatible Apple hardware, and the supplied connection details conflict, listing both USB 3.2 Gen 2×2 and USB 2.0/3.0. That ambiguity makes its headline speed harder to assess.

    Pros:
    • Listed read and write speeds reach up to 2,000MB/s and 1,800MB/s
    • Hardware encryption and password protection are paired with a touchscreen status display
    • Light 52g zinc alloy housing and magnetic design suit portable setups
    • Compatibility spans Windows, Mac, phones, cameras, and gaming consoles
    Cons:
    • At 1TB, it provides much less storage than the WD My Passport 4TB
    • The interface information conflicts between USB 3.2 Gen 2×2 and USB 2.0/3.0
    • Direct ProRes recording depends on having a compatible Apple device

    Best for: USB-C creators and mobile professionals who need compact encrypted storage, want drive status at a glance, and can confirm their device supports the stated connection and any ProRes workflow.

    Not ideal for: Buyers prioritizing multi-terabyte backup capacity, or anyone who needs unambiguous interface information before choosing a drive for a speed-dependent workflow.

    • Capacity:1TB
    • Drive type:External SSD
    • Interface:USB 3.2 Gen 2×2 listed; product data also lists USB 2.0/3.0
    • Maximum read speed:Up to 2,000MB/s
    • Maximum write speed:Up to 1,800MB/s
    • Security and display:Hardware encryption, password protection, and touchscreen drive monitoring
    • Housing and weight:Zinc alloy; 52g
    • Compatibility:Windows, Mac, iPhone, iPad, Android devices, cameras, and gaming consoles
    Our verdict
    “Pick the OSCOO if portability, a live status screen, and high listed SSD speeds matter more than capacity and you can verify interface compatibility.”

How We Picked

I ranked these drives by how clearly their listed features serve the search for encrypted external storage. I gave greater weight to products explicitly identified as hardware-encrypted, then compared stated capacity, portability and the kind of drive each product is. I also considered how readily a buyer can distinguish security features from ordinary backup features: encryption, authentication, and recovery processes matter more here than capacity alone.

That approach puts the Apricorn Fortress L3 2TB first as the most security-oriented high-capacity option in the named group, followed by the Padlock models for buyers wanting dedicated encrypted portable storage at different capacities. The OSCOO earns a distinct place for its touchscreen and SSD format, though the provided product details give less information for comparing its security implementation. WD’s My Passport drives remain useful capacity-focused alternatives, but they rank below the explicitly encrypted models because their listed descriptions do not identify dedicated hardware encryption. I would verify current manufacturer documentation for encryption standards, compatibility, and recovery procedures before buying any model.

Factors to Consider When Choosing Encrypted External Hard Drives

Choosing an encrypted drive involves more than matching capacity to your file library. I’d first decide what kind of risk you’re managing—loss or theft, unauthorized access, or simply accidental deletion—then check that the drive’s protection and recovery process match that risk.

Confirm What “Encrypted” Means

A product described as hardware-encrypted is not automatically a complete security plan. Check the manufacturer’s documentation for the encryption standard, how authentication works, and whether protection applies to all stored data or only to a particular software workflow. A drive that requires a PIN or keypad can help protect files if the device is lost, but it cannot stop someone from accessing files after you unlock it on an already-compromised computer. Don’t infer encryption from a password utility or backup software alone. For sensitive work, compare the security documentation with your organization’s requirements before purchase.

Match Capacity to Your Backup Plan

Capacity should account for growth, not just the files you have today. Photo and video libraries can expand quickly, while document archives may remain modest for years. A larger drive can reduce the need to split a backup across devices, but keeping one copy of everything in one place still leaves you exposed to loss or failure. Consider whether you need room for versioned backups, which retain older copies after files change. Avoid buying on terabytes alone: confirm how much usable space your backup software and file system will leave available.

Choose a Drive Type for Your Routine

Portable hard drives and SSDs suit different habits. A hard drive can be a practical fit for a larger local archive that stays on a desk or travels occasionally; an SSD has no spinning disk and may appeal to buyers who carry a drive frequently. The product names here do not provide enough information to compare real-world transfer speeds or impact resistance, so check manufacturer specifications rather than relying on the label. Also think about cable and port compatibility with your computer. A fast drive offers little benefit if your backup connection or workflow is the bottleneck.

Plan for Forgotten Credentials and Recovery

Encryption makes access control meaningful, but it can also make forgotten credentials a serious problem. Before relying on a drive, read how PIN entry, lockout behavior, recovery, and password changes work. Find out whether a recovery key exists and where it should be stored separately from the drive. Never keep the only recovery information beside the device it protects. For a business or shared household, decide who is allowed to unlock the drive and how access will be transferred if the main owner is unavailable.

Separate Security from Backup Redundancy

An encrypted drive protects stored data from some forms of unauthorized access; it does not create a second copy or protect against every loss event. A single device can be lost, damaged, or fail, so irreplaceable files need another copy in a separate location. For a stronger routine, keep one backup disconnected when it is not being updated and maintain another copy off-site or in a trusted cloud service. Avoid leaving your only backup permanently attached to a computer, where malware or accidental deletion could affect it. Treat encryption and redundancy as separate jobs in your storage plan.

Check Compatibility Before You Commit

Confirm the drive works with the computers and operating systems you actually use, especially if it will move between devices. Some security features, formatting choices, or unlock utilities may behave differently across platforms. Ask whether setup requires a particular application, administrator privileges, or a connection type your computer lacks. For a touchscreen or keypad model, confirm that the authentication method remains usable in your normal environment. These details can matter more day to day than a small difference in stated capacity.

Frequently Asked Questions

Are the WD My Passport drives in this roundup encrypted?

The listed WD My Passport product names identify portable external hard drives but do not specify dedicated hardware encryption. I would not treat a drive as encrypted based on its brand or capacity alone. Check the exact model’s current documentation for encryption support and how it is enabled. If device-level hardware encryption is a firm requirement, the explicitly described Apricorn or OSCOO options are easier to assess from the information provided here.

Should I choose the Apricorn Padlock 1TB or 500GB?

The choice mostly comes down to how much storage headroom you need. The 500GB Padlock can suit a smaller, focused set of documents or a compact backup, while the 1TB version gives more room for expanding files and broader backup sets. Neither capacity alone tells you how well the drive fits your computer or backup software, so check compatibility and the manufacturer’s security instructions. If you expect your archive to grow, avoiding a capacity limit can be more useful than buying a smaller drive that soon needs replacing.

Is the Fortress L3 2TB a better choice than a WD My Passport 5TB?

They answer different priorities rather than offering a direct like-for-like choice. The Fortress L3 is explicitly identified as hardware-encrypted and is the stronger match here for buyers putting dedicated security first. The My Passport 5TB offers more stated storage capacity, but its listed description does not identify dedicated hardware encryption. Choose the Apricorn if documented device-level protection is your main requirement; consider the WD only after confirming its security features meet your needs.

Does an encrypted external drive replace a second backup?

No. Encryption can help limit access to data on a lost or stolen device, but it does not protect the only copy from hardware failure, damage, or accidental deletion. Keep another copy on a separate device or in a trusted off-site service, and avoid leaving every copy connected to the same computer. For important files, a backup plan should also retain older versions so an unwanted edit or deletion does not immediately overwrite the only usable copy. Think of encryption as access protection, not backup redundancy.

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

Recovery options vary by model, so check the manufacturer’s instructions before storing important data on a secured drive. Some devices may offer a recovery process, while others can restrict access after repeated incorrect entries or leave data inaccessible without the right credentials. Store any recovery key separately from the drive and do not rely on memory as your only record. If the device will be shared or used for work, document who can access recovery information and keep that process protected too.

Conclusion

For best overall, I’d choose the Apricorn Aegis Fortress L3 2TB when dedicated hardware encryption and substantial capacity are the priorities. The Apricorn Aegis Padlock 1TB is my best value in practical balance for buyers who want an explicitly encrypted portable hard drive without moving to the 2TB Fortress; the 500GB Padlock suits smaller file sets. For a best premium security-focused pick, the Fortress L3 is the clearest fit in this lineup, while the OSCOO 1TB touchscreen SSD is the specific choice for buyers who want an SSD form factor and screen-based controls. Beginners should favor a model whose setup, recovery, and compatibility instructions they can comfortably follow—not simply the one with the most capacity. If you need bulk storage more than dedicated encryption, compare the WD My Passport capacities, but verify the exact model’s security features before treating it as an encrypted drive.
