raid 5 is good over a single disk for the read speed and the fact
you can rebuild if a disk is lost. A raid 5 write includes the
additional overhead of calculating parity, no question about it.
My raid 1+0 spindles are faster than my raid 5 when it comes to
writes.

Care to explain how RAID5 will be faster for a redo log write, because I
don't have that understanding of it.
If I'm wrong, I welcome the correction.
