    Do you have any evidence?

    I know what I am talking about. We are working on the mass-product based
    on FreeBSD. This product will have to burn data CDs. We have tried
    compatibility of various media with `-s max', including very cheap ones
    and have never seen any corruption due to speed mismatch. Virtually all
    media available on the market today has a special track, which records
    its speed rating and manufacturer.

    Granted, some very old burners may not be able to correctly read and
    understand this data, but for the same age reason those drives are not
    likely to be able to write at more than 8x anyway (most likely even 4x).
    You will have big problems finding any CD-R media (even very cheap one)
    with rating < 32 on the market today, so that chances to "overspeed" the
    media with those ancient burners are quite theoretical.

    Based on that I think -s max is reasonable default.
