Secure 512 GB USB 3.2 Flash Drive

The Apricorn Aegis Secure Key 3NX 512GB is a hardware-encrypted USB 3.2 (Gen 1) Type A flash drive. It provides 512 GB of storage protected by 256-bit AES XTS encryption that is performed on the device itself. No software installation is required to secure the data.

Suited for users needing portable hardware

This drive suits professionals who must keep sensitive files confidential while moving them between systems with a standard Type A port. It is not for buyers who want a software-only encryption layer or who require a USB Type C connector without an adapter.

512 GB capacity with 171 MB/s read

The 512 GB capacity comfortably holds large media libraries, project archives and backups. Sequential speeds of 171 MB/s read and 160 MB/s write handle large file transfers efficiently. Very large multi-terabyte datasets will exceed the available space.

Questions about this item

Does the 512GB drive need a USB 3.2 (Gen 1) Type A port to reach its 171 MB/s read and 160 MB/s write speeds?

Yes, the USB 3.2 (Gen 1) Type A connector is required to achieve the quoted 171 MB/s read and 160 MB/s write performance.

Will the 256-bit AES hardware encryption work if I plug the drive into a USB 2.0 port on an older PC?

The 256-bit AES XTS encryption operates inside the drive itself, so it remains active on any USB port, though transfer rates will fall to USB 2.0 levels.

How can I confirm the 256-bit AES XTS encryption is active after I set my PIN?

The drive's keypad LED changes to a solid green state once the PIN is accepted and the encrypted volume mounts, showing the hardware encryption is engaged.
