High-capacity encrypted desktop storage

The Apricorn Aegis Padlock DT FIPS is an 18 TB external hard drive built for users who must keep sensitive data offline and under hardware control. It connects through a USB 3.2 port and requires no software installation on the host machine.

Upgrade from software-encrypted

Moving to this unit replaces drives that rely on host-based encryption or have no encryption at all, eliminating the attack surface created by drivers and background services. The jump is worth it when data must remain protected on embedded systems, diagnostic equipment or any host that cannot run additional software.

Limited by USB 3.2 bus speed

The interface caps sustained transfer rates at the USB 3.2 Gen 1 level, so large sequential workloads will not saturate faster internal buses. Buyers who need multi-gigabyte-per-second throughput or hardware RAID redundancy should look elsewhere.

Questions about this item

What USB port does the 18 TB drive need for power and data?

The drive connects with a USB 3.2 cable and draws power from the same port; a USB 3.0 or later port is recommended for full speed.

How do I set up the hardware PIN before the drive becomes readable?

Attach the drive, press the unlock key, enter a new 7‑15 digit PIN twice, then press unlock again; the drive will then appear to the OS.

Can the internal 18 TB mechanism be replaced if it fails?

The enclosure is sealed with hardened epoxy to meet FIPS physical‑tamper rules, so the drive mechanism is not user‑replaceable.
