To my knowledge, no readily available controller performs validation
on reads (not even for RAID-1 or RAID-10, where it would be pretty
straightforward).

Something like an Adler32 checksum (not a full CRC) on each page might
be helpful.  However, what I'd really like to see is something that
catches missed writes, but this is very difficult to implement AFAICT.
