Phoronix: Linux 5.8 To Support Emulating MLC NAND Flash Memory As SLC

The Linux MTD subsystem that abstracts raw flash devices will allow emulating MLC NANDs as SLC in an attempt to boost reliability...

It doesn't help with write performance, though.

I'd be really nice if the flash devices would expose some way of using different bit-densities on a per- erase block basis. I don't need the device to track which blocks are programmed how; a higher-level layer can handle that.

Among the other MTD work is support for "constrainted" controllers and a variety of driver updates.

Hmm... there is "constrained"...

What do you mean by that? can you make an example?

Per block would never be useful. But per partition would.
