i have 875's 825's, 810's, and 896's and several aic788x boards. the adaptecs
are onboard and true adaptec brand cards. the NCR's are Symbios, Compaq, ASUS,
and Tekram boards. i will replace those adaptecs with NRC's every time i get a
chance. the cable problems with AIC's are so bad, esp. with external cases
that you HAVE to have granite's cables. and still no guarantees.
my NCR's on the other hand, NEVER give me any trouble. even the ancient 810's
integrated into compaqs.
we get so much crap on this list from people with adaptec's that timeout when
they do something, and declare it is the raid code. i can tell you i have
pulled drives out of ncr machines during file ops that are hitting the disk,
and not so much as a peep. the AIC's will choke.
NCR all the way. (diamond fireport is a nice version. spend your 60 bucks on
another controller.)
thats my .02
