DB Logspace vs OS Swap

Hi there,

i have a Test installation on a Server with little Hardware.

The Server has 4 Harddisks. I created 2 Raid 0 Volgroups.

Depending on this conditions i have to take one disadvantage.

I know recommended is:

RAID 10 for DB Log

RAID 5 for OS (Swapspace)

RAID 10 for DB Devspaces.

What will be better in Performance?

If i put the DB Log and the OS Swap on one RAID and the DB on the other,

or the OS Swap alone, and the DB LOG and the DB Devspaces together?

(Server has Minimum RAM, so i expect more or less swapping)
