For installation of the harddisk. It's really easy vonstatten - you put the SATA-to-USB adapter, which also serves as a cover for the housing, the S-ATA port on the hard drive, the plate then slides into the case and introduces the enclosed screws. However, the housing is sized a bit too generous, so my hard drive had too much leeway in housing. Something ESD foam as spacers but Remedy has created and now the board budge the housing. Too bad, but I give you a star deduction.
The case does the job just fine; the hard drive is correctly recognized by all devices, and the data transfer is jagged vonstatten. The hard drive heats up in this process, of course, but because aluminum conducts heat very well, the hard drive can simply give their heat while operating, so as the "natural habitat".
The enclosed bag is a nice touch, the device is pocket-compatible. Very good!
All in all, a great USB enclosure for 2.5 "S-ATA disks. A strong buy recommendation.
