I have the device now for 3 years for data security in use. Connections were then USB 2.0 and eSATA, the latter was for me a buying criterion for fast data transfer. The necessary cables are included and the device has no trouble until today and has always run reliably. The surface is easily scratched, bit, so you should always use a soft cloth for cleaning. Otherwise, the device looks good and fulfilled quickly and reliably always his work. So I can issue a strong buy recommendation for this device, and hope that they will get me a while.
