    What is the largest capacity so far that you know of?

    Of all I know~
    I've seen one CD-R which could burn up to 800MB.
    I've seen all DVD-R which could burn up to 4.7GB

    I'm still wondering~
    How did it ever get to DVD 9 then in that case?
    Doesnt DVD 9 means that you could burn up to 9GB?
    But I've never seen a DVD-R cd that has such capacity~

    Any one of you has?
    Please share the information~
    Thank you very much~

    cd-r = ~700 megs (never seen 800)

    dvd-r single side = 4.7 gigs
    dvd-r dual layer = 4.7x2 gigs

    maybe. unless they fight amongst themselves so long that an even better format emerges and destroys both.
