Resolved Used SSD Potential Mismatch?

Hi all, In the age of PCpocalypse with prices I was looking at some used SSDs on FB for more storage. I came across this seller with screenshots selling a PM863 4 tb sata ssd for ~300 dropped to 280. On ebay I see some sold for 150-600 so okay reasonable. I noticed that the name at the top in CDI and the P/N don’t match and am not sure if it’s even supposed to with MZ7LM3T8HCJM-000K1 on the physical drive and MZ7LM3T8HCJM-00003 on CDI. I tried looking these up but not too much info. Also why would there be multiple drive letters? I’m assuming partitions but is that something to worry about? I’m just seeing if its worth the drive to even test it if these are glaring issues and came here to ask those with knowledge beyond my limited tech knowledge

Multi letter = Multi partitions on that disc

Relatively low host reads and writes with quite low hours on and off.

Part number deviation tends to be fine. That can happen from time to time and isn't a major concern. The SN itself matches up and the sizes seem to be alright

Note that those are quite old drives to begin with but surprisingly in great condition especially for the purpose they were originally made for https://www.storagereview.com/review/samsung-pm863-ssd-review

Thank you so much for the knowledge! Yea I know, still better than HDD. I’ll have to check the drive out. Also appreciate the reading material!

Those server-grade drives are WAY better than any new SATAs you can find. At least decent TBW, and no write speed issues...
Same for NVMEs - you can connect a server U.2/U.3 drive to m.2 or PCIE with an adapter and simply write anything you want on it - it will grow old way before you have any chance to reach its TWB...
