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.
Summary: Bought this to use with my MacBook. I was surprised at how small it is especially for the capacity. It is compatable with USB 3.0 and FireWire 800 which is what I planned to use it for. Unfortunately I didn't realize it doesn't come with the FireWire docking cradle which you will need. I spent another $45 and bought it direct from Seagate. It arrived promptly. I did need to do a little grinding on the plastic of the cradle to make it fit but now it works fine.
Summary: Works well, easy to set up. I don't leave it connected all the time, but when I reconnect it backup automatically again. The Seagate Wireless Portable external drive would be a good choice, but a bit much at the moment. make sure you have a blue 3.0 USB port in your computer to get the full speed.
Summary: This is my second Seagate backup. The first Seagate is still going OK after a year but lacks the capacity of this unit. Only time will tell how good any backup drive is. This unit replaced a Verbatim backup drive (western digital drive inside) that never should have failed after 3 years. I only hook up these units a few times every month for backup transfers so I expect many years of service, certainly more than THREE years.
