RAID 10 PCI controllers

RAID 10

— RAID 0 array composed of RAID 1 arrays. For more information about these formats, see the corresponding paragraphs; and such a combination to a certain extent unites their advantages and mutually compensates for their shortcomings. Thus, RAID 10 provides high read speed and at the same time is completely insensitive to single disk failure. In fact, half of the drives in such an array, or even more, can fail, and the array will remain operational if at least one working disk remains in each individual RAID 1 block. The main disadvantage of this format is the same as in RAID 1 — high redundancy.
