Rating: 5/5 GREAT looks and yes it's fast October 28, 2018 And as it is powered by USB, minimal clutter. I keep my imac photo library on it instead of using the internal as it is faster and I feel safer (use preferences then change the library after copying the library file over). I also use time machine to back it up, even though it is an external drive (delete it from exceptions to do it I think). Great setup.

Rating: 5/5 Great First Impressions March 5, 2017 Seems to be a great drive. I haven't lived with it for long, but it's a handy size and convenient to use. I may even get a second one.

Rating: 5/5 Reliablity is job #1, but speed sure is nice. May 31, 2016 This drive has an HGST disk, so it's reliable as pretty much anything on the market (see backblaze's published data, HGST is emerging as the winner for reliability).

What I didn't fully appreciate until I experienced it first hand, is how the vastly improved speeds make backups far less noticeable. That's nice, since this is backing up my laptop, and I often need to leave to go do something, and having an interminable backup gets in the way sometimes. Now it's over in seconds. (The previous drive was running on USB, but it's definitely noticeably faster than FW800 as well).

Lastly, the bus power keeps clutter down, which is also great. I even like the white indicator light. Oh, the case is solid, nice looking.

Highly recommend as a great option at a reasonable price.
