Not super related to this thread, but anyone mind sharing how they test drives after they get them? I got 2 Micron 5300 Max's a year or so back and they had 0.2 and 3.2 PBW, yes a 3PB difference from the same buyer (rated for ~24PBW). Both were literally the same POH ~19k so I have no idea what this madman was doing with them, but they both maintain ~500MB/s. I didn't think much about slowdowns because my experience with SATA SSDs has only been with new drives and in my regular use I've never noticed a significant (like >50-100MB/s) slowdown before death of consumer SATA SSDs. A drop of 10-20% even I'm fine with, but I also have one significantly worse.
I only started thinking of this now because I found one I bought is extraordinarily slow (still can return but I have data on it and I'm too lazy and the data isnt moving

). It's a Samsung 863 running at 100MB/s and it had only used 5% of it's write endurance and had 34k POH. Does only PBW factor into write slowdowns or do you consider POH as well? I've never really done more than checking SMART is good. Any suggestions?
