RAID 01 “the mirror of stripes”.
RAID 01 is another combination of RAID 0 and RAID 1 similar to RAID 10. It has many benefits because you are achieving the performance of RAID 0 with the redundancy of RAID 1. In the image above you see a perfect exempt of how a RAID 01 array is configured. Disk 1 and Disk 2 are striped and then mirrored with Disk 3 and Disk 4. This provides performance and redundancy.
RAID 01 can even support multiple drive failures as long as they aren’t on the same mirror. The only downside would be the cost of disks.
RAID 01 data recovery can be very difficult since every failed drive needs to first be repaired. The correct order is needed, block size, offset, and which drive failed first must be determined with hex.
