Customer Reviews
Back to topThis is my fourth OWC Mercury Elite Pro External Hard Drive. The others had a regular-sized power plug (see photo)—which easily nestled in with the other power plugs in my APC battery backup tower. This unit's power plug is huge! I had to power everything off and move plugs around to get it to fit. (And yes, I did try using the older plug, but it didn't fit into the back of the new HD.) Please consider that power plugs need to be small because the backup towers have them packed closely together. Otherwise, I appreciate the quality of the Mercury Elites. Thanks!
I would recommend this product to a friend!

This was a great deal on a Time Machine drive. At 12 TB, it should be in service for several years. BUT, it is pretty loud, and it makes sounds that do NOT make me feel confident about the long term prospects of this drive. I hope I’m wrong.
