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 :)
I would use Samsung PM897 rather than 990 pro, simply because PM897 is enterprise drive, and it should be more reliable.
Also, compare both drives DWPD, the higher it is, the more reliable drive is. https://www.kingston.com/en/ssd/dwpd
Thanks for the detailed explanation!
I hope it helps a bit.
Usually enterprise drives have the dwpd in their specs, and consumer grade not likely to have it.
