Or you would have to ahve limited resources, which the average home studio
has.  Remember it is NOT a linear degredation in available tracks when
adding recording and playback to the same drive.  You lose a LARGE chunk of
performance much faster.

Meaning, lets say, hypothetically a single 200 Gig 7200 RPM drive has the
capacity to do 32 tracks of playback(I pull this from my previous post, but
still consider it a vast estimation) in real life.

If you do one track recording, and 4 tracks playback, it does NOT equal 5
tracks of that 32 track capacity.  In fact more than likely you are probably
bordering on using up a third of that disk performance with just that,
instead of the sixth you might expect, due to the amount the head might have
to move around, to read from one section of the drive, and write to another.

Exactly how costly it is depends on many factors, how fragmented your drive
is, how much reading and writing, etc.  but the end result is the same.  You
can record much more reliably if you record to a drive that is only used for
recording, and read from a different drive.  And when you are talking about
something on a limited time frame, that reliability can be important, for
instance doing playback of backing tracks in a live instance, while
recording your performance, not exactly uncommon.
