6 TB encrypted desktop drive

The Apricorn Aegis Padlock DT ADT-3PL256F-6000 is a 6 TB desktop external hard drive with hardware-based 128-bit or 256-bit AES-XTS encryption. It is built for users who need physical security for large data sets without relying on software utilities. The drive unlocks via an onboard keypad using a personal identification number.

USB 3.0 interface limits

The drive connects through a USB 3.0 port and requires the included 12 V AC adapter for power. Transfer rates are bounded by the USB 3.0 specification and the mechanical drive’s 12 ms average seek time and 8 MB cache. It will not saturate faster host interfaces such as USB 3.1 or USB 3.2.

FIPS 140-2 Level 2 validation

The cryptographic module is validated to FIPS PUB 197 and meets FIPS 140-2 Level 2 requirements, a distinction often mandated for regulated workloads. Buyers who do not require certified hardware encryption should consider a standard non-encrypted drive instead.

Questions about this item

Which capacity should I choose for this Aegis Padlock DT drive?

The model ADT-3PL256F-6000 provides a single 6TB capacity, so no capacity choice is required for this specific part number.

What does the 256-bit AES-XTS encryption mean for daily use?

It encrypts all data on the drive in real time using a hardware engine, so files are protected automatically without any software installation or performance penalty.

What does the USB 3.0 interface limit in practice?

The USB 3.0 connection caps the maximum transfer rate at the interface's 5 Gbit/s signalling speed, which will be the bottleneck compared to the internal drive's 12ms seek time and 8MB cache.
