You trust Alan?  :)  You're braver than I am, after all of Telsa's stories
about broken hardware.

4 drives makes for a very nice RAID 10 (or 01, depending on how you think
about it) array.  Although I imagine that disk speed isn't that much of an
issue here.

Ah-ha!  Finally an area that I've qualified for.  There are a few options
here, but getting RAID 5 that's as fast as software RAID 5 is expensive.
The Mylex AccelRAID cards have reasonable performance and decent prices.
Mylex ExtremeRAID cards are very fast, but expensive.  The DPT SmartRAID V
cards worked well for me, but I'm somewhat wary now that they've been
purchased by Adaptec.  There are drivers available from them, but you have
to know who to ask, as they're not publicly available.  Those would be my
top choices for RAID cards, probably in that order.  Let me know if you want
more info,
