Raid 5 is perhaps the exception here. For Raid 5 a substantial amount of CPU
power is needed.

Also, Raid 5 is particularly inappropriate for write-heavy Database traffic.
Raid 5 actually hurts write latency dramatically and Databases are very
sensitive to latency.

On the other hand if your database is primarily read-only then Raid 5 may not
be a problem and may be faster than raid 1+0.
