I have two Promise Pegasus 2 systems, a R6 with 6x2 TB disks and a R4 with 4x3 TB disks.
At the moment both run on RAID5 with 10TB available on the R6 and 9TB available on the R4.
I would like to use one of them as a backup for the other. Am I correct in assuming that I could use RAID0 for both and have two 12TB disks as safety is not an issue if I use one as a backup disk?
Thanks for your advice!
