Actually, if you're going to rebuild the whole thing from scratch, RAID 0+1
(sometimes called RAID 10) is even better.
You get all the speed of RAID 0 distributed reads and writes and all the
mutual fault-tolerance of RAID 1 without the single-disk failure tolerance
of RAID 5.
..of course, this assumes that you're using a hardware (SCSI) RAID solution.

Hi, I had installed ISA in a server configured in Mirrored Volumes Hard
Drives.
I have read in Tom's book that it is better to use RAID 5 Volumes, this
because the access to the cache drive is faster, because it doesn't have to
write in two drives the same information.
Recently I have noted a slower access to Internet in my clients, although I
have incremented the percentage of RAM used for cache.
Do you think that I will get a better performance if I reinstall the hole
server, this time in a RAID 5 volume? or is there another way to solve this
without reinstalling the hole system?
Thanks.
