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: For use as a backup drive, I upgraded from a WD Elements SE 500 GB drive to this one. This one is somewhat faster - it benchmarks at 83.3 MB/s average read, 66.1 MB/s average write. The WD benchmarked at 69.5 MB/s read, 73.1 MB/s average write. Latency was 16.93 ms for this Seagate vs. 17.91 ms for the WD. It's quite quiet, although there's definitely a low clicking on write.
Pros: Fast, USM (which allows access to raw SATA ports)
Cons: Drive access light could be more informative
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.
