@kindex -read_speed set read speed
@cindex Read, set speed, -read_speed
Set the speed for reading. Default is "none", which avoids to send a speed
setting command to the drive before reading begins.
@*
Further special speed codes are:
@*
"max" (or "0") selects maximum speed as announced by the drive.
@*
"min" (or "-1") selects minimum speed as announced by the drive.
@*
Speed can be given in media dependent numbers or as a
desired throughput per second in MMC compliant kB (= 1000)
or MB (= 1000 kB). Media x-speed factor can be set explicity
by "c" for CD, "d" for DVD, "b" for BD, "x" is optional.
@*
Example speeds:
@*
706k = 706kB/s = 4c = 4xCD
@*
5540k = 5540kB/s = 4d = 4xDVD
@*
If there is no hint about the speed unit attached, then the
medium in the -indev will decide. Default unit is CD = 176.4k.
@*
MMC drives usually activate their own idea of speed and take
the speed value given by the burn program only as upper limit
for their own decision.
@*
Depending on the drive, the reported read speeds can be deceivingly low.
Often it is possible to achieve higher read speeds by bold values
like "20xDVD" or "16xBD".

Put out a list of speed values as reported by the drives with the loaded

The list of write speeds does not necessarily mean that the medium is writable
