Hey one comment on this. With dell Perc3/DC  you should check the
megaraid-devel list to find the best BIOS settings for maximum
performance.  There have been many comments on it and trials to get it
going really well.  All told though I totally love the LSI Megaraid (
which is what the perc3/dc is ) controllers. We use the Elite 1650  with
seagate cheetah drives for a nice little array.
