Mariss,

You will probably get as many different answers as there are replies,
but here's my 2 cents

DB9 connector on each card for the following reasons.

I may have my drives in different areas so I don't need to make
a special cable with a DB25 on one end and branch it off in all
different directions

DB9 because a surplus serial cable can be used, it's allready
shielded and looks neater when routing it around a machine if
need be.

Stick another DB9 as the S & D input to your drives
and it would make a real neat package, plug and play.
