I ordered two of Transcend hard drives with 2 TB and had much in operation. Unfortunately, the USB connection is very shaky to the housing and there is only slight vibration / or if you have the hard drive in operation move a little to disconnections. So if you just copy a file and something shakes a little disk separates briefly the connection and restores them, with the result that data transfers be interrupted briefly and then most could be continued only with errors.
Strangely, I had these crashes also, although wobbled nothing, so you could never be than an hour away and leave what copy because it has come permanently to crashes. This really is very annoying and shame is especially since advertised with a very resistant hard drive that then the connection and something else was saved, I can not understand!
As data grave the hard disk is possibly suitable, safe but not as an external hard drive for long-term use!
