18 TB encrypted desktop drive

The Apricorn Aegis Padlock DT provides 18 TB of storage in a desktop form factor with hardware-based 256-bit AES encryption. A built-in keypad unlocks the drive without software, keeping data secure on Windows and macOS systems. Super Speed USB 3.0 connectivity enables fast transfers for large media libraries and backups. The drive is TAA compliant for government and enterprise procurement.

USB 3.0 port and power requirements

Verify that the host system has an available USB 3.0 Type-A port or a compatible adapter for the supplied cable. The desktop enclosure requires its own AC power adapter, so a nearby mains outlet is necessary. USB 2.0 and 1.1 ports will work at reduced speed if no USB 3.0 port is present. No driver installation is needed for basic operation on supported operating systems.

Rugged enclosure with integrated keypad

The sturdy chassis protects the internal mechanism during stationary use on a desk or shelf. A water-resistant keypad handles daily PIN entry without wearing out, and the lock indicator gives immediate visual confirmation of the drive state. The attached USB cable reduces clutter and avoids lost connectors. Fanless construction keeps noise to a minimum in quiet office environments.

Questions about this item

Does the Aegis Padlock DT 18 TB drive ship with a USB 3.0 cable and power adapter, or must I buy them separately?

The drive includes a Super Speed USB 3.0 cable and an external power adapter in the box, so no separate purchase is required for basic operation.

Is the 18 TB model the only capacity available in the ADT-3PL256 line, or are smaller versions offered?

This specific model provides 18 TB of storage; other capacities in the Aegis Padlock DT family are sold under different part numbers.

What real-world transfer speed can I expect from the USB 3.0 interface when the drive is connected to a desktop PC?

The drive uses a USB 3.0 interface with an 8 MB cache buffer; actual throughput will depend on the host controller and file types but will not exceed the USB 3.0 specification limit.
