It's good to know about RAID levels 1, 2, 3, 4, 5, 6.
[2] http://en.wikipedia.org/wiki/Nested_RAID_levels
For nested RAID levels (hybrid RAID), which combines 2 or more standard RAID levels, there are:
01, 03, 10, 50, 60, 100.
In [2], it says:
According to manufacturer specifications and official independent benchmarks,[8][9][10]
in most cases RAID 10 provides better throughput and latency than all
other RAID levels except RAID 0 (which wins in throughput). Thus, it is
the preferable RAID level for I/O-intensive applications such as
database, email, and web servers, as well as for any other use requiring
high disk performance.[11]
So RAID 10 seems a widely used configuration.
