Pioneer 109 w/ Wytron 399 - Takes too long!

I have a tower w/ 9 x P109 and 1 x P109 (acting as a writer)
Wytron 399 Controller

Got it last year.
Always write at 4X
Full burn used to take no more than 16min
Now, its averaging 60+ min.

Any suggestions?
I am going to start by replacing the writer (with a new P111) - but I really don’t think it’s that…

Thanks for any posts.


The controller is the only problem.

Should I change the controller? Ugrade Firmware?

Thanks for your help

First try to enable DMA for all drives.

Maybe also upgrade the firmware if possible.
