I wish manufacturers exposed a way to manually provision the drive as all SLC / MLC / TLC, a small SLC cache drive would be great for several use cases.

- userbinator 4y agoI'd gladly pay the same price for a 40GB SLC SSD over a 120TB TLC one, but the former is going to have an endurance >100x more, and that's apparently why there's seemingly no cheap SLC SSDs available. The capacity increase with more bits per cell is multiplicative, but endurance and retention get exponentially worse. Manufacturers would rather go the planned obsolescence route even at the same prices. (SLC also needs far less fancy ECC and wear leveling algorithms, to the point that early SSDs with only SLC didn't have anything but 1-bit ECC and no wear leveling; I still have a 64MB USB drive with a full binary capacity and it would theoretically be capable of 6.4TBW before wearing out.)
