@hitmanbabyvn I usually go with SM953's for lower capacity drives if possible. They are both a bit older. Based on the specs there, maybe that is a case for PM.
Mine just arrived today. Surprisingly clean drives free from dust and well packaged. Has anyone checked how much data has been written to these?
I also received mine today and it's almost new. Here's the smartctl -x output:
smartctl 6.5 2016-05-07 r4318 [x86_64-linux-4.16.15-200.fc27.x86_64] (local build)
