RAID 10
Advantages Disadvantages
Implemented as a mirrored disk array
whose segments are RAID 0 disk
arrays

multiple stripe segments Very high disk overhead - uses only
50% of total capacity

General file server
RAID 30
Advantages Disadvantages
Good for large files with high transfer
rates where extra fault tolerance is also
required Random write performance only fair.

throughput
