the TR1 drive I have holds a max of 800MB. So eventhough CDR/CDRW only 
holds 650MB, the read/write speed more then makes them most effiecent for
me.  Of course if you have better hardware, YMMV.

I hope you recycle when you're done with them.  I do. Please do your part 
for the environment.

tell me how this is any different then your tape drive.  What do you do
if your drive will no longer read tapes?   at some point you have to draw
the line.
