Advantages Disadvantages

Medium Write data transaction rate
Good aggregate transfer rate
Safest RAID level, except for RAID 60
High disk overhead – equivalent of two
drives used for parity
Slightly lower performance than RAID 5
Advantages Disadvantages
Implemented as a mirrored disk array
whose segments are RAID 0 disk
arrays
High I/O rates are achieved thanks to
multiple stripe segments
Very high disk overhead - uses only
50% of total capacity
Advantages Disadvantages
Good for large files with high transfer
rates where extra fault tolerance is also
required
Random write performance only fair.
Disk failure has a medium impact on
throughput
