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 :)
