Bests & Worsts Reviews from Amazon

I recently purchased this drive and was so disappointed with its performance. I had purchase a MY Essential Passport 1TB 2 months prior and expected the same kind of performance. A 1 hour backup on the older drive was taking more than 8 hours on this drive. I stopped the backup and I ran Atto benchmark on this drive. Out the box and it was rate at 25-30 MB/s which is USB 2.0 speed. I Have a My Essentials Passport (which is also USB 3). So I took the cable from that drive and ran the benchmark, it read/wrote at 115-120 MB/s which is what I expected in terms of performance from this drive; its very close to eSata speeds with the proper cable. I changed USB 3 ports and saw no change in performance. I reattached the original cable provided and the speed went to USB 2. I contacted WD technical support and was told that I had a defective cable and that I would receive one in 4-5 days. When I got back from vacation the cable had arrived and I ran the ATTo benchmark against the drive. Initially it was performing properly, but when it got to the 1024 test it failed. From that point on this drive with the new cable performed at 25-35 MB/s. I called support again, told them their cable does not support the drive. Yet if I put the working cable from the other drive in either USB 3 port, the drive worked great. I was told by the support person I spoke to at WD that they would overnight a new cable and that it would arrive by Tuesday. As it's now Thursday and a new cable has not arrived I can only surmise that these cables are defective and not USB 3 rated. I have spoken to tech support twice and have been told that the cables on it's way. I finally convinced them to give me a tracking number. Well the status says it hasn't been picked up. Now if you have a cable problem fess up and give a date-certain as to the delivery? I tire of calling and getting the same answer. It's all about the cable with this item, if you got it (the proper USB 3 Cable) you can expect the performance gains, because I see them. I just have to remove the cable from my other drive to see it.
