I kinda like to spread my redo to several disks

I have 4 disks and i write the redo logs as follows

Disk1 - OS
G01_M1 on disk2
G01_M2 on disk3
G02_M1 on disk3
G02_M2 on disk4
G03_M1 on disk4
G03_M2 on disk2

and so on

this way redo is safe from disk failure.

Hey all,

If you had 8 disks in a server what would you do?  From watching this
list I can see alot of people using RAID 5 but i'm wary of the
performance implicatons.  (

I was thinking maybe RAID 5 (3 disks) for the OS, software and
backups.   RAID 10 (4 disks + 1 hot spare) for the database files.

Any thoughts?
