Bests & Worsts Reviews from Amazon

3+ days after beginning a copy of my Time Machine backup (approx. 2 TB), it had yet to complete the copy. It was reading "2 hours remaining" when the copy ultimately failed. I restarted immediately, and here I am 7+ days after it all began and it's stating "2 days remaining." Incidentally, this new drive was purchased to replace a different drive that was dropped from the rotation after it catastrophically failed losing all data. That drive was a Seagate. So disappointed.
