More predictable performance under heavy load (nfs kernel server,
typically). BTW the 3Ware is not a very good sata controller; I've found
that it is actually one of the worst of its class when it comes to
IOPS, the Areca 16xx, LSI Megaraid and Adaptec 5xx5 all perform better
as simple controllers in combination with MD (tested with 8 SSDs).
