HI David,
our experience is, that RAID 5 is the better solution
here is our configuration
Compaq Proliant 5000 4 x 166 MHz Pentium PRO
256 MB RAM
NT 3.51
ORACLE 7.3
for the System disk 4 GIG mirrord (harware)
2 x RAID 5 each 5x2 GIG
the size of the DB is about 13 GIG and we have about 120 users
with RAID 5 you need less numbers of disks (reducing costs)
because the security informations are striped over all the disks
in your RAID5 set
for example for a Volume with 10 GIG net
you need for RAID 5 (when you are using 2 GIG drives)
6 drives
for mirrored you need 10 drives
the performance of the mirrord version is better but our experience on
the COMPAQ PROLIANT boxes with RAID 5 is very good
be carefull with your ORACLE configuration
(witch tablespace on wich volume ....)
if you need more information, let me know
