Architecture

Hello,
I want to kow if the following architecture is good :
Disque 1&2 ( Raid 1)
c: OS
d: sqlserver + system tables + log files
Disque 3&4&5 (Raid 5)
e: dataIf you don't plan on having any volume it would be fine. Otherwise, it would suck. A 3 disk RAID array is the slowest RAID 5 configuration possible. In addition, if you want high performance you should have the tempdb and/or the log files on seperate disks.

If you only have five disks though, this should work.
