Thanks Bruce. It does seem to have a very good SCSI adaptor built into it,
and I have two PCI slots free after installing the 10/100 ether card -- much
faster than a [non-cardbus] pcmcia card.
From where I sit, it seems as if the price penalty for non-ATA drives is about
the same across the three current technologies. About a 50% premium here in
Silicon Valley.
I'm not sure if USB storage devices are supported on FreeBSD, but they
probably are on a later version. Not sure about FireWire support - might be
there for the taking from the Darwin folx.
Prior to the iMac, scsi was my storage subsystem of choice as it ran on
everything I had in the house. Ugh. Time to research drivers and interface
cards.
