Funny that it reports DVD 4x write speed since it's just a CDROM.
Even more funny is:
Maximum read speed: 29551 kB/s (CD 167x, DVD 21x)
Current read speed: 256 kB/s (CD 1x, DVD 0x)
Maximum write speed: 176 kB/s (CD 1x, DVD 0x)
Current write speed: 0 kB/s (CD 0x, DVD 0x)
Buffer size in KB: 5645
Impressive read speed. Too bad it's not noticed when I am actually using
the drive.. :-)
