Buffalo Technologies (http:///www.buffalotech.com) has announced the MiniStation Cobalt USB 3.0 portable hard drive, the latest generation of SuperSpeed external storage solutions that deliver interface speeds up to 5 Gigabits per second.

Ralph Spagnola, vice president of sales at Buffalo Technology, says that Cobalt USB 3.0 is backward-compatible with USB 2.0 and it works with Macs and PCs. Apple hasn’t added USB 3.0 support on any Macs, so the drive will run at USB 2.0 speeds.

The MiniStation Cobalt HD-PEU3 will be available in a variety of capacities up to 640GB and will begin shipping in April. It’s backed by a limited one-year warranty.
