Seagate GoFlex Desk STAE123 External Storage Controllers (FireWire 800, USB 2.0) for External 8.9 cm (3.5 inch) hard disk drives (Personal Computers) 5
This part is one of the few that are better than their description. First, the foundation: The Seagate hard drives on this adapter is intended (GoFlex Desk, Backup Plus Desk), can be operated with various "base plates" (either USB 3.0 or Firewire 800 + USB 2.0 or Thunderbolt). Such base plate is this adapter. Will you be using the drive on the FireWire 800 port of the Mac, which comes with the disk base plate is drawn (usually well-USB 3.0) (Carefully lift possibly, the plastic anchors can quite firmly adhere) straight down now and put the hard drive to the Firewire adapter. Done. What is not in the description (at least I have not found it) is that the adapter with FireWire 800 cable, USB 2.0 cable and a complete power supply with 5 network adapters is (for sockets probably almost all over the world) delivered. So you need to buy anything extra. The speed seems to be in order: The activity of my Macs showed (with short break-ins) when backing up fairly consistently 58 MB / sec.
