Oh well....glad I bought some spares. 8-)

I got a pile of 4-port 3ware escalade cards for $150 each at
www.thelinuxstore.com. That's a pretty steep discount since
they promised me a bunch of 2 port cards and then flubbed the
order. So you may pay the going rate for them which is about
$279...still pretty darned cheap. I've been too lazy to shop
around for a better price. Here are some benchmarks I posted
a while back. I'll hunt around for the same benchmarks with
4 drives. These cards have made it rather painless for me
to have a RAID 1 config with machines that aren't I/O-hungry
and RAID 0 configs for those that are. Unlike the software
RAID stuff, you don't have to hunt around the planet for
patches and tools when you need to upgrade kernels. Current
2.2 and 2.4 kernels come with the 3ware drivers.
