Note that RAID-1 is the second worst-case for mail server

write (or re-write) an entire RAID block at once, plus the parity
information.
Coming late into the thread...
What is a good raid level for a maildir IMAP server? RAID 10 (or 0+1 as
others call it).
If you're using maildir, that is one of the situations which works pretty well
with RAID-5, although RAID-10 is also (always? :-) a good choice.
