We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

I'm not so good with specs and I'm trying to decide which of these 2 drives is the most reliable. I'm not looking for speed, I want to make sure my data is safe (as it can be!).

Samsung 990 Pro 4TB specs:

- PCIe Gen 4.0 x4, NVMe 2.0
- Samsung V-NAND 3-bit MLC
- 5-year or 2400 TBW limited warranty

Samsung PM897 3840GB specs:

- SATA 6.0 Gbps, 2.5 inch
- Samsung V6 (128 Layer) TLC V-NAND
- DWPD: 3.0 (5yrs)

I'm a newbie, but I did catch that "3-bit MLC" is, in fact, TLC. But I have no idea what V6 TLC is and how it compares to the consumer TLC :)

The PM987 would have a 21.024 PBW endurance rating compared to the 2.4 PBW of the 990 Pro. Not sure if it has PLP though but it looks like it has the capacitors for that feature based on the pic from TPU.
