# Debian uses wodim, CentOS uses the older/original cdrecord
# $ man wodim
#   speed=#
#          Set the speed factor of the writing process to #.  # is an inte-
#          ger,  representing a multiple of the audio speed.  This is about
#          150 KB/s for CD-ROM,  about  172 KB/s  for  CD-Audio  and  about
#          1385 kB/s  for  DVD media.  If no speed option is present, wodim
#          will try to get a drive  specific  speed  value  from  the  file
#          /etc/wodim.conf  and  if  it cannot find one, it will try to get
#          the speed value from the CDR_SPEED environment  and  later  from
#          the  CDR_SPEED=  entry  in  /etc/wodim.conf.   If no speed value
#          could be found, wodim uses a drive specific default speed.   The
#          default for all new (MMC compliant) drives is to use the maximum
#          supported by the drive.  If you use speed=0 with a MMC compliant
#          drive,  wodim will switch to the lowest possible speed for drive
#          and medium.  If you are using an old (non MMC)  drive  that  has
#          problems with speed=2 or speed=4, you should try speed=0.
