Micron had some 32GB SLC flash chips.
But they may have been discontinued before
any number of them shipped. An Amazon seller claimed
to be selling an SLC 32GB flash stick, which is normally
not something you can find. And they mentioned the
part number of the flash, and it really existed.
But today I can't find it any more. SLC would be
good for 100K writes. The more normal TLC or QLC
are a lot lower. You can find tiny (industrial) SLC
flash sticks, but maybe 1GB or 2GB or so. Legacy stuff.
The 32GB one was unusual.
