It looks to me, reading your message more carefully, as if you've decided
to use a U320 (parallel SCSI) RAID array.

It is correct that there are almost no Ultra320 PCI-Express cards on the
market.  I'd still urge you to consider PCI-X where you have a wealth
of options for an Ultra320 SCSI adapter (I can make some specific
recommendations if you want).  However, if you really want to go with
PCI Express, you *can* use a card with an onboard RAID controller and
simply not use the RAID portion of the card, either via SCSI pass-through
or by configuring a single JBOD volume on the RAID card.

The one that looks most likely to work with NetBSD is the LSI MegaRAID SCSI
320-2E.  You may find a limit of 2TB on the size of any individual volume
with this card, however (you could probably arrange to have this fixed by
porting, or hiring someone to port, the latest version of the 'amr' driver
from FreeBSD).
