Although it's at a block, rather than file, level; perhaps the work on
bcache could be useful?
"Instead of using just memory to cache hard drives,
he proposes to use one or more solid-state storage

block device cache)."

Presumably there's no reason the same code and approach couldn't be
used to cache "slow flash" on "fast flash".
