Hi,

We use SSA disks for all of our storage pools in a Raid-5, 6+P (6 drives
plus parity drive) configuration. We are about to reconfigure our
storage pools and we are reviewing our options.

I'd like to get some idea from other as to whether 6+P is appropriate.
Would less data drives per parity drive offer significantly greater
protection? Or are we able to increase the number of data drives without
significantly reducing our protection?
