If your primary workloads for this array are mostly single user/thread
streaming writes/reads then this may be fine. If they are multi-user or
multi-threaded random re-write server loads, re-write is the most
important metric and you should optimize for that scenario alone, as its
performance is most dramatically impacted by parity RAID schemes such as
RAID 6.
