RAID 0+1 is implemented as a mirrored array whose segments are RAID 0 arrays
RAID 0+1 has the same fault tolerance as RAID level 5
RAID 0+1 has the same overhead for fault-tolerance as mirroring alone
High I/O rates are achieved thanks to multiple stripe segments
Excellent solution for sites that need high performance but are not concerned with
achieving maximum reliability
|
RAID 0+1 is NOT to be confused with RAID 10. A single drive failure will cause the
whole array to become, in essence, a RAID Level 0 array
Very expensive / High overhead
All drives must move in parallel to proper track lowering sustained performance
Very limited scalability at a very high inherent cost
