Wow, why was the TBW halved? New NAND process?

I remember SSD lifespan going down between the Samsung 470 (32nm flash) and its successor the 830 (20nm flash), and going down even further with TLC flash.

Doesn't seem to affect the average lifespan (it's more data than most people will write) but still, it would be nice if they lasted longer instead of being ultrafast.

970 Pro was MLC, 980 Pro is TLC (they call it 3 bit MLC)

>980 Pro is TLC

Any news on 980 Evo? Considering this downgrade, I'd assume Evo will run on QLC.

Ah, that explains it.

I checked Samsung server SSD SM863a MZ-7KM960N 960 GB. They claim 6,160TBW. It's using SATA and much slower than M.2 SSD though.

But server hardware is more expensive and can be harder to get.

They really should make a "high endurance" SSD model for consumers. I think many people would like that over benchmark speed. Personally, I can only saturate SATA 6 Gbps when doing backups.

In 2D MLC era, 50-75TBW for 500GB drive was common. Now in 3D TLC era, 300TBW for 500GB or more is common. It's enough endurance already and that's why industry moving torward 3D QLC.
