Secure desktop storage

The Apricorn Aegis Padlock DT is a 3.5‑inch external hard drive built around 256‑bit AES‑XTS hardware encryption and a 20 TB capacity. It targets professionals and organisations that must keep large data sets protected without relying on software tools.

USB 3.0 connectivity and power

The drive connects through a Super Speed USB 3.0 port that remains backwards compatible with USB 2.0 and 1.1 hosts. An 8 MB cache buffer assists sustained transfers, while the desktop form factor means the unit requires its own power supply and a free USB‑A socket on the host system.

20 TB capacity ceiling

Twenty terabytes provide room for extensive media libraries, long‑term archives or full‑system backups. The hardware‑encrypted design secures every byte at rest, but the single USB 3.0 link and mechanical platters set the practical throughput ceiling for workloads demanding sustained multi‑gigabyte‑per‑second rates.

Questions about this item

What is the sustained throughput limit of the USB 3.0 interface on this 20 TB drive?

The Super Speed USB 3.0 interface caps sustained throughput at the bus maximum, which is the first bottleneck you will hit during long transfers.

How much heat or noise does the 3.5" mechanism produce when running continuously?

The 3.5" form factor runs quietly and stays cool enough for all-day operation without added cooling.

Which host ports and cables are required to use the drive with its hardware encryption?

Any USB 3.0, 3.1 (Gen 1) or 3.2 (Gen 1) port works; the drive is also backwards compatible with USB 2.0 and 1.1.
