Linux has some alternative filesystems in the standard kernel that are
specifically designed to include wear-levelling in their storage-
allocation algorithms.
The firmware in SSDs that makes it pretend to work like a hard drive is
very complex, and of course it has bugs. It would be nice to be able to
simplify things by getting rid of most of that layer.
