External storage has predominantly moved to USB 3.0 ever since the interface has become standard on both Macs and PCs. While everyone is already enjoying faster connectivity, Buffalo is raising the bar with its latest DriveStation DDR. The aptly-named external USB 3.0 hard drive is joined by an unprecedented 1GB DDR3 RAM. So everything going in or out of the DriveStation will first get cached in the memory. The buffer greatly benefits small file transfers which are often associated with multiple handshakes, creating overheads that slow down throughput.
