There are some cases where a single large drive will perform better
than two smaller ones.  A lot of controllers out there in PC-AT land
are not as smart as many of us would like.  For instance, the Western
Digital 1007-WAH controller has a 16K track buffer on it.  If you have
one disk, it helps with performance.  If you have two disks, 
performance gets worse because it can't use the track buffer as much
as with a single disk (it has to be flushed before it can read/write
to the other disk).  With this particular controller, one 300 MB is
better than two 150's.

If you have multiple controllers or SCSI your statement would be very
true though.
