The Arecas are a lot faster than the 9550, more noticeable with disk counts
from 12 on up. At 8 disks you may not see much difference.
The 3Ware 9650 is their answer to the Areca and it put the two a lot closer.
FWIW we got some Arecas at one point and had trouble getting them
configured and working properly.
