In the broadcast field (yes - I know that the recording techniques are 
different - but the media isn't) it is generally accepted that used but not
worn-out tapes are best for archival storage.  Has something to do with the 
original-factory-fresh erasing done, and that it takes several recording
erasing cycles to make the tape really "take" a recording well.

I have heard this arguement applied to Video tapes as well.

My guess is that - at least to some extent - it would be true for digital
tapes as well.
