This is an extremely poor product. Do not purchase if you care at all about the information you're storing on the drive. Our company purchased 7 last year to help back up other drives and free up space on our server. Now 2 sound like they're on their last leg. These drives were not being used as a primary storage system thankfully. While used infrequently, they still manage to sound as if we just asked them to run a marathon. They wheeze, whine, and are exceptionally slow. I don't trust it and have stopped using the drive.
