A USED Samsung 840 PRO 256GB SSD. It was used for nearly 4 years as a first-level backup drive. There is an attached CrystalDiskInfo screenshot for basic SMART data on this drive. The drive is in good physical condition with the exception being that there is a small piece of the corner-L plastic chipped off on the male power plug (please reference the images). The drive is, also, in good endurance condition.

This will make a great small capacity backup or recording/scratch drive. It can be used as a great cache drive as well. I'm not going to go into great detail about how the older 2-cell MLC drives, made using older nodes, have much higher endurance (higher rated P/E cycles) and how it is an older SATA III interface in a 2.5"x7mm form factor. If you know, you know.
