You will not come close to saturating even a 40MB/s bus with a single
10K rpm drive.  Since latancy is not dominated by the bus, you would
probably see no performance benefit at all by going to a different card.

Faster cards do exist but are considerably more expensive.  I doubt they
would be worth it in your case.  The 53c875's definately have the best
support.  If you intend on using many drives on this system eventually a
dual channel card may be a good bet.
