If you use RAID5 remember that you loose the disk capacity of one disk for = the RAID configuration algorithim storage ie: four 10 gig drives equates = to 30 gig storage RAID5. If you use RAID5 you can loose one disk and still = be able to recover the data that you have storred in the configuration and = the disks are prefferably "hot swaps". RAID5 disk configuration is best = used for read type data, the performance drops drasticly on updates,inserts= ,deletes because of the writing to the data area and the algorithim area. RAID5 is good but it does not follow OFA for disk layouts and i/o = contention. 2bits worth.
