First USB 3.0 Portable Drives Hit Market

USB ports connect host devices, such as PCs, to other devices such as printers and storage drives. USB 3.0 increases bandwidth and transfers data close to 10 times faster than USB 2.0. The USB 3.0 interface can offer a transfer rate of 5G bps (bits per second) compared to 480M bps per second for USB 2.0.

Super Talent is offering three USB 3.0 flash drives with capacities up to 256GB. The line achieves data transfer speeds of up to 125M bps. A 32GB drive goes for $120, which is relatively expensive compared to USB 2.0 thumb drives.

External hard drives were some of the earliest USB 3.0 devices to come out last year, but OCZ this week announced Enyo USB 3.0 solid-state drives. The SSDs will be available in capacities of 64GB, 128GB, and 256GB. The drives offer up to 260M bps read (around 1.5G bps ) and 200M bps write capabilities. The USB 3.0 drive also is backward-compatible with older ports.
