Seagate BlackArmor PS 110 USB 3.0 Performance Kit
USB 3.0 is fast—fast enough to copy a 100-gigabyte video library in about 20 minutes. Seagate's drive was the first to make that speed accessible. Thanks to USB 3.0's five extra connector pins and a faster-spinning hard drive, the PS110 copied data three times as fast as a USB 2.0 model, and it bundled a converter to upgrade any laptop to 3.0 through its ExpressCard slot, paving the way for the company's current GoFlex hard drives. $180.
