RAID 5+0

Index| Features| RAID 0| RAID 1| RAID 1+0| RAID 2| RAID 3| RAID 4| RAID 5| RAID 5+0 | RAID 6|


RAID5+0 stripes data across mulitiple RAID5 groups using a front-end RAID0 method.
Such multiple RAID5 striping enables one disk per group to be saved in the event of disk failure. This provides higher reliability in large-capacity configuration systems compared with a single RAID5 group. In addition, the rebuilding of transactions, which with RAID 5 and RAID 6 takes an increasingly longer time as disk capacity grows, can be executed much faster with RAID5+0 as the amount of data in each RAID group is smaller.
