Seagate has a USB 3.0 external drive, too

Well, how about that: WD isn't the only major hard drive vendor with a USB 3.0 external product. Seagate now sells the BlackArmor PS 110, a "USB 3.0 performance kit" that includes a 500GB hard drive and USB 3.0 adapter card.

Where the WD solution we saw yesterday looks geared for desktops, the Seagate bundle should suit laptop users better. The 500GB drive has a 2.5" form factor and a slender, 0.5"-thick enclosure, and Seagate's USB 3.0 adapter is of the ExpressCard variety. Oh, and the BlackArmor PS 110 kit includes USB power and data cables, so users won't need to hunt for an AC outlet.

In spite of its mobile pedigree, that 500GB drive sounds plenty quick, too. It has a 7,200-RPM spindle speed and can purportedly deliver a sustained transfer rate of 100MB/s over a USB 3.0 connection—about three times what's possible over USB 2.0, Seagate says. Should you happen to lose track of the ExpressCard adapter, the drive will work via USB 2.0 at a reduced speed, of course. Seagate completes the bundle with "Acronis business-grade backup suite, automated full-system backup and SafetyDrill+ software, a bare metal recovery feature." The spec sheet also mentions 256-bit AES encryption.

The BlackArmor PS 110 can be bought directly from Seagate's website right now for  $179.99. That's the same price as the standalone 1TB WD drive, although this bundle does include more goodies and a more portable drive with a longer warranty (five years instead of two for WD).
