A few hundred files is not an issue.

smartd is a handy tool.  It's warned me of impending doom at least twice
tha I can remember. Like anything that logs/sends email, you have to
configure it to ignore the irrelevant stuff, or you risk training yourself
to ignore smartd's warnings.

It is supported in Debian, along with robust recovery tools.  I'm using XFS
on my data array currently.  I chose XFS primarily because I deal with
large (1GB +) files.
