Apricorn Aegis Padlock 3.0 1000 GB portable hard drive

What the drive is

The Apricorn Aegis Padlock 3.0 is a 1000 GB portable hard drive with on-board 256-bit AES-XTS hardware encryption validated to FIPS PUB 197. A built-in keypad lets users enter a PIN before the drive mounts, removing any software layer and protecting against key-logging attacks. It connects via SuperSpeed USB 3.0 and remains backwards compatible with USB 2.0 and 1.1 ports.

Who it suits and who it does not

This drive suits professionals and organisations that require hardware-based, software-free encryption with a physical keypad for regulatory compliance or high-security workflows. Buyers who need higher capacities, solid-state speeds, or a drive that unlocks purely through host software should consider other options. The mechanical hard-disk mechanism also makes it less suitable for environments with severe vibration or shock.

Behaviour under sustained load

During extended transfers the drive operates at the mechanical limits of its internal hard disk rather than the 5 Gbps USB 3.0 ceiling, so sustained write throughput will settle at typical rotating-media rates. The encryption engine processes data on the fly without adding measurable latency, and the enclosure dissipates heat passively without active cooling. Performance remains consistent across long sessions as long as the host port supplies adequate bus power.
