If these are 8 external disks, then RAID 0+1 is the best choice (IMHO) since you have both performance and redudnacy. RAID5 should only be used with SAN boxes, which use it whether you like it or not. and OS can be on RAID1 if you need redundancy... I/O on those fs is not *that* critical anyway. hth Alan Bort Oracle Certified Professional On Wed, Apr 8, 2009 at 12:47 AM, dave <david.best@xxxxxxxxx> wrote: > Hey all, > > If you had 8 disks in a server what would you do?
