Distributions shipping with recent kernels offer many RAID level
options: 0, 1, 5, 6, 10 with many per level options. Even though
the installers makes it easy to setup the RAID, it is not so easy
to decide what level to pick. Especially with 5, 6 and 10, there
doesn't seem to be a clear winner. How do slashdotters decide
which level to choose? Do you run benchmarks on each level? Is
there a set of "official" benchmarks? How about disaster
recovery?
