Its usually not a good idea to make a single raid5 set much over 7-8 disks as the repair time becomes brutal, and the performance degradation after a single drive failure is extreme. For very large numbers of drives, build multiple raid5 sets and stripe them (raid 0+5 sometimes called raid 50). I will say again, I really prefer mirroring and raid 10/0+1 ... disks are cheap, data loss and/or downtime is expensive.
