Thanks.  I googled around and found this page:


Which says what each model is.  It looks like the "RAID" controller they 
wanna charge me for is about $500 or so, so I'm guessing it's the medium 
range Elite 1600 type controller, i.e. U160, which is plenty for the 
machine / drive number we'll be using.  

Has anyone played around with the latest ones to get a feel for them?  I 
want a battery backed controller that runs well under linux and also BSD 
that isn't gonna break the bank.  I'd heard bad stories about the 
performance of the Adaptec RAID controllers, but it seems the newer ones 
aren't bad from what I've found googling.
