use the second disk for raid1 or mysql?

[punchbowl]

moving mysql to the secondary disk seems like a good idea but then setting the two of them up as raid1 does too.

Can I have my cake and eat it somehow?

centos5.2 btw

If you want more I/O go for mysql on secondary disk, and remember to keep backups offsite, as RAID-1 isn't a substitute for backups.

so it's an either or situation. I should just go for centos with no raid and mysql on the second disk? I'm already backing up offsite daily.
