This Buffalo DriveStation DDR 3 TB Hard Drive isn't your standard USB 3.0 hard drive. It has a trick up its sleeve.

Instead of writing and reading right from the hard drive itself, the DriveStation has 1 GB of RAM serving as a large cache, meaning I/O can peak at 408 MB/s. Combined with the crazy speeds of USB 3.0, this edges the DriveStation into SSD-territory.

And that's never a bad thing.
