Excerpt: Its very useful to backup all your pictures. USB 3.0 is a plus. The UI for FB and FLICKR backup could be better. But the transfer speeds between computers are really amazing provided you use USB 3.0 port.
Pros: Compact, Easy To Set Up, High Capacity, Portable, Quiet
Summary: I bought this external hard drive to back up my Dell PC internal 500gb hard drive. I found that the larger size works well due to the normal loss of disk space from the nameplate capacity due to pre-loaded file structure, software, etc. It is working fine.
Summary: Have an iMac with USB2 only, so fast external drives are limited. Got a deal on this one for $149. (1TB drive plus thunderbolt adapter). Backing up a 600GB drive right now. Sustained write speeds of 85MB/sec. The other drive is also on TB, but I doubt it matters since the bus has plenty of capacity. Not earth shattering but faster than USB2 (my other option). Will update when the backup is done, but it should be done in a couple of hours.
Fast drive, Thunderbolt adaptor portion works only with laptop drives.

Summary: First of all, note that this is really a Seagate Thunderbolt adaptor with a drive included. You can easily remove the included drive, and attach any other SATA 2.5" (laptop) drive - you just can't use the included case for any other drive as far as I can tell. That wouldn't be much of an issue though, I use bare drives all the time.
