Nested RAID levels - Wikipedia, the free encyclopedia
" It is not as robust as RAID 10 and cannot tolerate two simultaneous disk failures, unless the second failed disk is from the same stripe as the first. That is, once a single disk fails, each of the mechanisms in the other stripe is single point of failure. Also, once the single failed mechanism is replaced, in order to rebuild its data all the disks in the array must participate in the rebuild. . The exception to this is if all the disks are hooked up to the same raid controller in which case the controller can do the same error recovery as RAID 10 as it can still access the functional disks in each RAID 0 set. If you compare the diagrams between RAID 0+1 and RAID 10 and ignore the lines abo" [1]

" RAID 0+1 (also known as RAID 01 or RAID 0/1) uses a mirrored configuration of two striped disk sets; RAID 1+0 (also known as RAID 10 or RAID 1/0) is a stripe across a number of mirrored sets. RAID 2 � eliminates the 100 percent redundancy overhead of RAID 1 by using a powerful error detection and correction code (Hamming), with bits of the data pattern written across multiple disks. RAID 3 � similar to RAID 2, but uses a single check disk per group that contains the bit parity of the data disks; data is interleaved across all disks. Because disk reads are performed across the entire array and all data is transferred to the controller in parallel, RAID 3 is well suited for applications that require high data read/write transfer r" [2]
