I have the device complete with 4 hard drives equipped (1.5TB, 1.5TB, 1TB, 0,75TB) and use it over the USB port as a data buffer. An eSATA connection is also possible, however, because the data is not as often as required, USB is sufficient for my needs from perfect. The installation and connection is done in 5 minutes. Windows has recognized all the board immediately and now the machine is on my desk and hums softly to himself.
Thanks to this case, I can now dispose of several single housing and have again lots of free USB ports and sockets.
