Mike -

Even without concurrent IO, it helps to have the data across 2 different drives - it minimizes head movement on each drive.

If you have all the data on one drive, the heads could be flying from the beginning of the disk to the end for all of the accesses. If the data is on 2 drives, the files are likely to be closer together on each drive. And the heads would travel less.

There seems to be no concurrent IO on NT - the dll no uses multiple threads to read the database, but shows no improvement on an IDE system.
