The media code is CMC MAG-M01-00 . The burner does see it as 2.4x, 4x, 6x and 8x capable. I just burned a few more disks. They went all the way to 8x and not back down. Total burn time was about 8 minutes. I guess it's not consistent.
I always do verification on the disks. The read time was 9 minutes 39 s. So that's a total of about 18 minutes to do burning + verification.
Is there a burner that can cut down that total time significantly, eg. for example in half ?
