THE ULTRASTAR 7K4000 4TB SATA III

The rugged design housing HGST has been using with their 3.5" Deskstar and Ultrastar lines has always been my favorite.

The large sticker placed at the top of the drive states the available drive capacity, drive sectors, serial number, country of manufacture, factory roll-out date, electrical requirements, current firmware version, SATA connectivity (6Gb/s = SATA III), RPM speed (Rotations Per Minute) and several certification logos.

All 3.5" hard disk drives feature the same 3 standard mounting holes on each side.

The various PCB components have been moved on the interior side for increased protection (always compared to older models).

At the rear of the drive we see the usual SATA III connector (again nothing new here, only SAS connectors are different).
