Summary: I have dozens of these 1TB hard drives installed in various external enclosures, RAID5 arrays, and NAS units. They do the job and most of them seem to last about 3 years of 24x7 operation before they fail. I can live with that considering the price.
Summary: This item works well. It is a good replacement drive. Seagate makes it easy to return drives if they fail during the warranty, very simple exchange, they provide the packing ... you pay $10 for the shipping the new drive arrives ... that is it. Takes a few minutes to set up by phone.
Summary: PROS: Inexpensive. Fast. Easy to install. Great backup drive. CONS: None. I recently built a computer and bought two of these for my applications. They were easy to install and are fast at processing my data.
