These are used Samsung 1TB hard drives in perfect working order. I'm selling a total of 3 and all are identical and were purchased at the same time. The drives were bought in 2010, but have only around 250 days of powered on usage each (see photos). The low usage is due to the fact that my NAS was only powered on when I was actively running a backup of my main system every few months. Otherwise the system was shutdown until it was needed for another backup.
