I bought these drives in Grade B condition and used them in my personal PC for a Plex Media Server since 2022. I used them largely uninterrupted for just about over a year and they served me very well. I am only selling because I upgraded drives.
The drives are in good working order, and are particularly great for personal file servers or generally storing large quantities of files. The material the drives are made of leads to this smudging (see second picture) but this is not dirt or filth, the drives are generally clean, dust free, and do not have any major scratches or dents.
