That would be 24220008448 bytes (~24.2GB)
growisofs pre-formatted the disc for 24.8GB
It took approximately 85 minutes for the dd read,
so dd read the disc at a rate around 4.75 MBps.
Maybe not really really slow, but still slow.

The same one that is fast on the windows machine.

The only way to verify this is to traverse through all
of the files in the iso image (mounted loopback) and
diff them with files on the blu-ray disc. No thanks.
I trust that growisofs recorded properly.
> CentOS experiment with growisofs
Yes, but now I need to focus on cdrecord on solaris10.
How will the CentOS experiment help me with that?
