It be nice if manufacturers provide a way to downgrade SSD to SLC via some driver settings.

While ssds do not, all flash chips do. So if you were ever going to try building your own SSD or simply connect some flash directly up to your soc via some extra pins, you would be able to program them this way. I imagine extending NVMe to offer this is possible if there was enough popular demand.

Great thing about disks is that they don't require drivers at all. The driver settings Windows app is not going to be open sourced if such thing were to exist.

but how would they make more money?

  • I'd buy such a device. Currently in holding on to my last pair of SSDs from pre-QLC era, refusing to buy anything new

    • There are still new SSDs that use TLC, such as the Silicon Power UD90 (I have one in my system). Not only that, some of them will run in SLC mode when writing new data and then move the data to TLC later - advertised as SLC Caching - which could be even better than always-TLC drives (even ones with a DRAM cache).

    • The point I was making is that there is no profit to be made by extending the life of drives. And sample size of one (i.e. you) is not representative of the market. There is always a demand for storage and people will keep buying worse products because there is no other choice.
