Keeping sensitive files on an external drive can be convenient, but ordinary storage is not enough when a drive may be lost, stolen, or accessed without permission. An external hard drive with hardware encryption protects data at the drive level, helping keep files unreadable without the correct credentials.
This roundup compares portable and desktop options from Seagate, WD, and Apricorn, with capacities ranging from 500GB to 22TB. Use the buying guide below to match encryption, portability, capacity, and backup features to the way you work.

How We Picked the Best External Hard Drive with Hardware Encryption
We focused on drives that offer hardware-based security or a clearly documented password-protection system, while also considering capacity, portability, connection type, backup tools, and everyday usability. The selection includes dedicated encrypted Apricorn Aegis Padlock models, Seagate One Touch drives with password-activated hardware encryption, and WD models that pair password protection with backup or ransomware-defense software.
Because security features vary, check the manufacturer’s current specifications before buying. A drive advertised as password protected is not automatically equivalent to one with dedicated AES hardware encryption.
Quick Comparison
- Best for dedicated hardware encryption: Apricorn Aegis Padlock models with keypad-based access and AES XTS encryption.
- Best portable capacity range: Seagate One Touch and WD My Passport models from 2TB to 6TB.
- Best for large desktop backups: WD My Book models with 18TB or 22TB capacities.
- Best compact encrypted option: The 500GB Apricorn Aegis Padlock for smaller sensitive data sets.
Key Buying Factors for an External Hard Drive with Hardware Encryption
Encryption and Access Control
Look for the specific encryption standard and how credentials are entered. AES XTS hardware encryption and an onboard keypad can provide strong protection without relying entirely on host-computer software. Password recovery is often limited or impossible, so secure your credentials and understand the reset policy.
Capacity and Expansion Needs
Choose capacity based on both current files and future growth. Two to 5TB is generally practical for travel, documents, photos, and moderate media libraries. Desktop drives from 18TB to 22TB are better suited to large backups, archives, and shared workstations, but they require a power adapter and are less portable.
Portability and Connectivity
Portable drives draw power over USB and are easier to carry between computers. Desktop models can offer much more capacity but need a fixed workspace. USB 3.0 is suitable for many backup tasks, although actual transfer speeds depend on the drive mechanism, computer, cable, and file sizes.
Backup Software and Workflow
Password protection secures access, while backup software helps preserve files when a computer fails or is hit by malware. Consider whether you need scheduled backups, ransomware defenses, device-management tools, or compatibility with your operating system. For important data, keep an additional backup in another location.
Who Should Buy Which External Hard Drive with Hardware Encryption?
Choose an Apricorn Aegis Padlock if protecting confidential files is the priority and you want dedicated hardware encryption with keypad access. Select a Seagate One Touch model if you want a portable drive with a straightforward password-activated security feature and familiar capacities.
WD My Passport models are a practical choice for everyday portable backups, especially when you value included backup software and capacities up to 6TB. Choose a WD My Book desktop drive when maximum capacity matters more than mobility. Whichever model you select, use a strong unique password, safely eject the drive, and maintain a second backup for irreplaceable files.
