I bought this and haven't used it much. The reviews for this hard-drive seem to indicate that it is prone to failure. I haven't had it fail on me but I do experience a clicky noise. The build quality of this hard drive is very poor. All 4 of the rubber feet have come off. At times, the hard drive won't register when connected via usb. If you are looking for something more reliable, it is probably best to look for an ssd. I only have 50gb stored on it, so I probably won't ever exhaust it till it fails.
