AFAIK, the many small disks model still provides faster disk times than
the single large media.

The purchasing trend though seems to be towards fewer, bigger or cheaper
media. I've no idea if the newer disk improvements outperform multiple
older disks though. So the performance loss may not be as bad as it seems.
