Digitizing Digital Audio Tape: Testing Two Approaches

The Stanford Media Preservation Lab has kicked around the idea of building a dedicated Digital Audio Tape (DAT) "ripping" workstation around a Digital Data Storage (DDS) drive for a few years, but we never pursued it in earnest. We assumed the benefits of using a computer drive to read audio DATs largely centered around extraction time and reporting. Transferring a DAT in a conventional deck is done in real-time, whereas a DDS drive, we were told, would rougly cut the time in half depending on the speed of the drive (Peter Oleksik's retrospective on the Fugazi archive mentioned speeds up to 4x real-time using the DDS method with a Sony SDT-9000 drive and DATXtract). We also liked the idea of accompanying logs identifying where dropouts occurred. Still, we were skeptical whether such a system would be better than one designed around multiple conventional decks. Was there a way to test both methods without investing a bunch of money in late 1990s computer components?
