Floor (RKS+H1J) Model
About 5 million hour or longer (in RAID 5 configuration)
RAID 6 configuration:
(MTBF of the disk drive)

(MTBF of the disk drive)
n(n−1)×Number of Parity group×MTTR
RAID0 configuration
MTBF of the disk drive
n×Number of Parity group
RAID1, RAID1+0 configuration
(MTBF of the disk drive)
n×1×Number of Parity group×MTTR
