Nice. Seems to me that it'd be nicer to have an interface to raw flash (no wear leveling, direct access to erasure, read, write, read-modify-write [as an optimization]). Then the filesystem could do a much better job of using flash efficiently. But a raw interface wouldn't be a disk-compatible interface.
