Performance___________________
Can backup 22.66GB per disc with "Mac & PC" format.
Disc takes about 21 minutes to burn, about 19 or less to verify. 40 minutes total per disc.
Toast progress screen varies but reads something like...
"Average write speed: 4X"
"Current write speed: 7X"
However the estimated time remaining in Toast's progress screen was way off from the real time at completion.

NOTE - You do not need the $19.99 "HD / BD plug-in" to make blu-ray data discs.
You do need to install a system extension called "RoxioBluRaySupport.kext"
The installation of that extension is done by Toast, it comes with Toast, no extra cost.
Toast installs that system extension to allow your Mac to read Blu-ray and HD DVD discs, to
mount them on the Desktop when you insert a Blu-ray disc into the external drive, the Mac OS
does not support blu-ray still as of November 2009.
The Blu-ray system extension and the $19.99 "HD / BD plug-in" are two different things.
