Note that there are several different RAID controllers you can get with
a DELL. I had good luck with the PERC 4C (AMI MegaRAID based) at my
last job. In a dual 2400Mz machine with 2 gigs ram, it handily outran a
4 way (about 1200 MHz CPUs) windows / MSSQL box with 4 gigs of ram at
most tasks. Especially inserts / updates. The windows machine had the
more generic PERC 3I type controller in it.
