Ok... that might be the best you can get speed wise with the above
system. You should be able to milk alot more performance out of that
card if you put it in a newer system.

I don't see any problem doing that... FreeBSD would only care if it
was the boot drive AND if it also changed the device name in /dev. So
yes... try it... if it changes the /dev name just edit /etc/fstab with
the new settings.
