Rocstor Rocbit 2A 160GB Portable Drive

The Rocstor Rocbit 2A is a 160GB portable hard drive with a 2.5 inch form factor. It spins at 5400 RPM and offers 8MB cache for everyday storage tasks. Hardware encryption using DES or TDES at 40, 64, 128 or 192 bit protects data at rest. USB 2.0 and Firewire400 interfaces provide legacy connectivity for older systems.

Suits Mac users needing encrypted legacy storage

This drive suits buyers who require hardware encryption on a compact drive with USB 2.0 or Firewire400 ports. It is not for users who need higher capacity than 160GB or faster transfer speeds than the legacy interfaces allow. Buyers with only modern USB-C or USB 3.0 ports should look elsewhere. The 5400 RPM speed limits performance for intensive workloads.

Hardware encryption secures data at rest

The defining specification is the DES and TDES hardware encryption supporting 40, 64, 128 and 192 bit keys. This feature keeps data confidential by preventing unauthorised access without software overhead. Anti-shock protection adds physical durability for mobile use. Plug-and-play connectivity simplifies setup on compatible Mac and PC systems.

Questions about this item

How much heat or noise does the 5400 RPM drive produce during continuous all-day use?

The 2.5-inch 5400 RPM mechanism with 8 MB cache runs without a fan, so it stays cool and quiet enough for desktop use throughout the day.

What ports must my computer already have to use the USB 2.0 and Firewire400 interfaces?

You need a standard USB 2.0 Type-A port or a Firewire400 port; the drive includes both cables for plug-and-play connectivity.

Will the hardware encryption work with an older Mac that only has Firewire400?

Yes, the DES or TDES encryption at 40, 64, 128 or 192 bit operates independently of the interface, so it functions over Firewire400 on legacy Macs.
