If you want to higher R/W performance, you should go for raid0. raid0 fragments the data into the number of disks and distributes them. It gains a big performance. One drive fails, however, all data gone. raid5's benefit is not the speed but the effective space usage with the least data redundancy. Bitwise parity calculation consumes lots of processing power. So raid5 is the least choice in terms of performance. -john On Thu, Apr 10, 2008 at 6:43 PM, Jerry Geis <geisj at pagestation.com> wrote: > Hi all, > > I was wonder what experiences there are out there with using RAID-X for > performance increases.
