In the past I've had systems with RAID cards: LSI and Adaptec. The
LSI 320-2X is the fastest one I've ever had. The adaptec ones suck
because there is no management software for them on the newer cards
for freebsd, especially under amd64.
The system I'm working on now is thus:
Sun X4100 M2 with an LSI 4Gb fibre channel card connected to an
external self-contained RAID enclosure, the Triton RAID from Partners
Data. The Triton unit has in it an Areca SATA RAID controller and 16

It is only 2Tb raw, 1.7Tb formatted :-) I just used sysinstall to
run fdisk, label, and newfs for me. Since it is just postgres data,
no file will ever be larger than 1Gb I didn't need to make any
adjustments to the newfs parameters.

I splurged for the 10kRPM drives, even though they are smaller 150Gb
