Summary: We used these with a large number of Macs for support - working in IT, these things are a godsend. Not only does it work very fast as a thunderbolt target device, but the connector for the disk is just a SATA connector - so you can use the thunderbolt drive sled as an impromptu Thunderbolt disk...
Summary: We noticed a tendency for the unit to send the disconnect error message (we use Mac) after the computer wakes. Most USB storage (i.e., thumb drives) don't do that. It became annoying and my wife stopped using it. On the plus side, it packs a lot of storage in a small space!
Only one thing that keeps it from getting five stars
17 April 2014
Summary: I love everything about this product. It does everything it is advertised to do perfectly. I couldn't be more pleased with the product itself. However, the only reason it gets four stars from me instead of five stars is because of lack of instructions.
Summary: The Seagate Backup Plus 1TB Portable External Hard Drive has been one of the most reliable external hard drives I've ever used. I've had a lot of luck with Seagate external hard drives, and so far this one has been holding up well.
Summary: For some reason, I just have this affinity towards anodized aluminum, and this drive looks great next to my mac. It comes with the drive, the USB cable, and some junk info from Seagate. Per other reviewers' recommendation, I didn't bother to mess with the Seagate dashboard stuff.
