Note that large-cache controllers mitigate RAID-5's write overhead.

Over course, they cost more, blah blah, but when you are putting
together a few TB worth of SCSI disks, RAID-5 becomes a necessity
(unless you have the deepest of pockets), and so the cost of such
up-scale controllers isn't so horrible.
