The drive can specify the writing speed by the SET STREAMING Command.
The performance setting is persistent and remains until a new descriptor is sent, so even if the disc is
changed, the previously set writing speed is available. However, only for CD media, the writing speed can
be set also by a SET CD SPEED command.
The performance settings for CD and DVD are not independent from each other.
The available writing speed may be restricted by the drive when the characteristic of media is not suitable
for the speed.
