agreed.

with the "latest" ide tech, it's not even too bad as a server...basically
you want to make sure your frequently accessed data is on a separate IDE
bus than your system drive, since only one device can use the IDE bus
at a time.
moreover, make sure your busses are actually distinct from the computer' s
point of view---i hear tell that some (most?) dual-channel onboard IDE
setups treat the two channels as one (one interrupt? not sure, i read
it somewhere tho...and im gullible and believe everything i read as long
as its not about or from microsoft =)), meaning you'll may want a separate
IDE card to run the high-access drives off of.
i've heard really good things about the Promise IDE Raid card under
windows...and ISTR seeing linux drivers for it too. ~$150.
i'm days away from implementing a full sunsite + other goodies mirror
via the two onboard IDE channels in a 1.5 year old dell optiplex for
open UT usage and possibly some outside usage...i'll tell you how it
scales (as well as announce to the list the URL once it goes gold)
i still prefer scsi, but since the people financing this venture have
a finite pocketbook and the other piece of it is buying me a new laptop--
i cheaped out =)
