Secure portable storage

The Apricorn Aegis Padlock Fortress provides 1TB of encrypted storage in a compact 4.7" x 3.3" x 0.75" enclosure. It uses a built-in keypad for PIN access and requires no software or drivers to operate. The drive is validated to FIPS 140-2 Level 2 and uses 256-bit AES XTS hardware encryption. It weighs 0.39 lbs and includes a travel pouch.

Build integration

A USB 3.0 interface with a supplied Y-cable connects the drive to any compatible host for power and data. The 5400 RPM mechanical drive offers an 8MB cache and 12ms average seek time. Its water and dust resistant case protects the keypad and internals during transport. Unattended auto-lock secures data when the drive is disconnected.

Suitability

This drive suits users who need hardware-encrypted portable storage with physical keypad entry and certified validation. It is not suited for buyers who want solid-state speeds or silent operation. Those needing a purely software-managed encryption layer should look elsewhere. The mechanical design also makes it less suitable for high-vibration environments.

Questions about this item

How long before the 5400 RPM drive throttles during continuous large-file writes?

The 5400 RPM mechanism with 8 MB cache and 12 ms seek time will hit its sustained-transfer limit first; expect performance to level off once the internal buffer fills during prolonged writes.

What are the heat and noise levels when the Fortress runs all day?

The fanless aluminium case stays warm but silent; the 0.39 lb, 4.7 x 3.3 x 0.75 in enclosure dissipates heat passively so noise remains at zero decibels.

Which host port and cable are required to unlock and power the drive?

A USB 3.0 Type-A port supplies both power and data through the included USB Y-cable; no extra adapter or software is needed.
