hey charles - i've used these guys in the past to build some relativly
cheap fast storage for some video playback systems:
they have a 1U 4 disk external controller, as well as "shoebox" systems
depending on what form factor suits you. we also used the Internal SATA
to External adapters which worked pretty well. The cables are actually
compatible with infiBand - so if you got an IB system laying around you
are all set :)

i've been a fan of building raidz pools using ZFS lately. except for
super high performance workloads it works quite well and you can config
it to have double parity drives in your pool plus hot spares.
sun just released a patch to solaris 10 that allows you to drop in SSD
drives into your zpool config which can be used as caches which
in theory should give similar benefits of RAID controllers with BBU's.
but thats solaris not in fbsd yet...soon hopefully though :)
