I own a few external hard drives that require electrical outlets for power. Cuts down on the mobility. My biggest concern in purchasing this particular drive was that there seemed to be a lot of ambiguity regarding whether or not it would work with Macs. In fact, I even asked the question..."Will this work with my Macbook?" and someone posted a simple "No." That was helpful. Didn't give any personal anecdotes to back up that answer...just simply, no. After reading many more reviews and doing more research of my own, I decided that customer may have accidentally answered my question when they were actually thinking they were answering another customers question regarding whether or not Matrix Revolutions was a good movie. So I took a risk and purchased this little gem and strangely enough...it worked on my Macbook Pro right out of the box. I did format the drive so that I can export large files and use with Macs and PCs (if anyone would want to do that sort of thing.) And if you want to learn more about that, you can check this out:[...]But besides that...it was ready to use right away without any issues at all. I love it. Simple, easy to take anywhere...lightning fast...able to export ginormous files at once. The price is great. Oh...and did I mention that it WORKS GREAT with Macs?

I have bought a few of these, and one out of 10 i had to send back. i love them. none of them has crashed on me . nock on wood.

I bought the Passport Ultra to backup my files and family photos. It is easy to use and I have had no problems with the unit. I'll buy a 4TB next time.

Really good hard drive with a decent speed and a surprising small format. Excellent for doing backups or storing and streaming multimedia in your network.

Very easy to use, this mini 2T USB 3.0 Hard Drive is amazing! Fast, small, it fits everywhere and does not take too much place on a desk.

Cheap. And they keep getting cheaper. I will get an average of 25-27 mbps of transfering on these. Owned mine for about a year and it's still going strong.
