Thanks! That's just the sort of info I am looking for.
I am definitely going with the fastest scsi drives I can get.
Probably a 6 or 8 disk system. Is there a huge jump between using 4
and 6 drives, or 6 and 8 drives?

somewhere in the $7k - 15k range. The post important things are
write speed to the disk and good linux driver support for the raid

It'll depend on what you're planning on using it for. Performance
requirements, capacity
and so on.
For fast writes you'll probably want something like RAID10 with
lots of spindles. SCSI
is likely to be somewhat faster, but a lot more expensive. For SATA
RAID most people
like the 3ware and Areca cards. I'm using this system, from ASA,
for pretty much that
and it seems OK. 5U server, 24 external bay, 2 internal bay
capacity. And it's opterons,
which seem to be a bit more PG-friendly than Xeons. It uses the
3ware 9550SX card.
(The general opinion here seems to be that the Areca cards are
somewhat "better"
than the 3wares, but a lot more expensive).
