Re: With 4 disks should I go for RAID 5 or RAID 10

RAID 10.

I snipped the rest of your message because none of it matters.  Never use
RAID 5 on a database system.  Ever.  There is absolutely NO reason to
every put yourself through that much suffering.  If you hate yourself
that much just commit suicide, it's less drastic.
