PCI controllers with RAID 0+1 support

RAID 0+1

— RAID 1 array made up of RAID 0 arrays. See the respective sections for details on both; and their combination allows you to combine the advantages and to some extent compensate for the disadvantages of both options: the array turns out to be fast and at the same time resistant to failures of individual disks. However, in terms of fault tolerance, this combination is still inferior to RAID 10 (see the relevant paragraph), and therefore is used somewhat less frequently.
