We updated one of our data transfer drives to USB3 for faster speed. But why go with a plain silver case? This Vantec case looks great, has a VERY quiet fan to keep the drive cool (which you can turn off) and makes drive installation a snap. If you have an external hard drive that is only USB2 and you have a new USB3 capable computer (Look for the USB symbol with SS or SuperSpeed above it) – a simple case upgrade can drastically increase the speed of the external drive.
