Uhmmmm, maybe read the _entire_ paragraph?
"The concept that SATA subsystems will tend to consume more CPU cycles because
SCSI controllers have onboard processors is somewhat nullified when considering
controllers such as the Areca 1210 and the 3Ware type of products."
Which means to say that with the advent of more modern approaches the current
SATA controllers and hard drive subsystems consume less cycles than their early
IDE predecessors. Whether or not the difference is now more or less than SCSI,
the delta is probably small enough to be nearly negligible.
What I was really trying to build up to was there exists other parameters on
which to base decisions, a couple of which seem to get left out most
discussions I've seen.
OT - now I'm really not happy. Upgraded to KDE 4.1 Beta 2 and now finding more
brokenness than either 4.0.4 or 4.1 B1. Add to the list Knode no longer has the
ability to word wrap. Ughhhh!!! Upgrade to the newer, better, more
feature-laden and watch stuff break. Just got to love "programeritus". Just how
is it a Beta 2 can be *so* much worse than anything that went before...
