we have DELL 6800 server with 12 internal disks in it.  O.S. is CENTOS 4.6 and SCSI control card is PERC 4e/di.

We plan to configure 4 disks (5,8,9,10) as RAID5 or RAID50.  This logical volume will be use as file systems and store database backup files.

Can anyone tell me which one is better on performance?
