Here's a really nice chart that I ran across in the online release notes of SAN/iQ v8.5, which will help explain the differences between all of the SAN/iQ Network Raid levels, especially since there were some name changes to the levels between 8.1 and 8.5.
Notice the big difference between the Raid 10 levels and the Raid 5 & Raid 6 levels are Raid 5 & 6 are stripes with parity based, while all of the Raid-10 levels are stripes with mirror based.
Hope it helps and any questions, feel free to post a comment! ;-)
