Rated 5 out of 5 by from Excellent quality bought this a week ago and I'm very happy with the quick delivery and of course you wouldn't expect anything less from Seagate. I absolutely love it. The hard drive itself is slightly chunkier than the slim hard drive, but it's still very easily portable. I'm quite liking the diamond patterns on the cover as well. Also the cable that comes with it is very stable when plugged in

Rated 5 out of 5 by from Super-fast speed. Huge Capacity. Economical price. This Seagate Expansion Portable External Hard Drive USB 3.0 looks beautiful as an external drive. Overall, it has a solid value but low in features but is an excellent drive to store or access your files and applications instantly, as it has a super-fast speed and a huge storage capacity.

Rated 4 out of 5 by from Works Great I needed more storage and was recommended to buy an external hardrive. I'm so glad I did! I have had this product around a month and all of the annoying pop-ups that my cloud was full have all stopped because the photos are now stored on this. I'm very happy with the product
