For Mitsubishi 24x/40x media, some people have reported that even 52x works, but my drive spins down at the end when trying 48x, and burns unreadably discs at 52x. Therefore, I only state 40x as maximum speed for these.

As a general remark, it seems to be a bad idea to overburn when writing at 52x. The drive spins down at the end, or it just stays buzy, without writing anything. This could be caused by using media which is not certified for 52x recording, so we will know more as 52x media becomes available. From the table you can also see that Smart-Burn did not always detect the highest possible speed.

Next, we are going to check the drive's performance with non-standard discs...
