And one more way.
If neither your database nor filesystem do checksums on
blocks (seems the compressing filesystems mostly do checksums, tho),
a one bit error may go undetected corrupting your data without you
knowing it.
With a filesystem compression, that one bit error is likely to grow
into something big enough to be detected immediately.
