I'm setting up an 8 drive SATA array that will either be configured RAID 5 plus a hot spare or RAID 6, with each incorporating all 8 drives. The chassis and controller both will have an 8 drive capacity, so all bays and connections will be utilized. In either case, I likely won't keep an additional cold drive on hand, so consider that if there's a drive failure it will likely be a few days before I receive a replacement drive.
What would be the advantages of one setup over the other? The way I see it, I may as well use RAID 6, but maybe there's some reason to use RAID 5 with the hot spare.
