This is all well and good, but may not sufficiently cover over the
Vital Problem with IDE drives, namely that they are likely to cache
writes and not tell the 3Ware controller about that.
It would doubtless be a slick thing to have an IDE RAID controller
with cache (that might well overcome some of the traditional problems
with IDE), but that only forcibly helps if you can turn off write
cacheing on the drives.
