||Data Striping and Mirroring
||Data Striping with distributed parity
||Data Striping with two distributed parities
|Number of Disks
||4 or 8
||Highest performance with data redundancy; higher write IOPS per Parity Group than with similar RAID‐5.
||The best balance of cost, reliability, and performance.
||Balance of cost, with extreme emphasis on reliability
||Higher cost per number of physical disks
||Performance penalty for high percentage of Random Writes
||Performance penalty for all writes
