A rip of an XGD2 game is 7,838,695,424 Bytes (7.8 GB); A rip of an XGD3 game is 8,738,846,720 Bytes (8.7 GB).
The difference is about 191 MB that gets cut off at the end if you do not use the Burner Max firmware. Keeping this chunk of data intact on the backup is what the iXtreme Burner Max was created for. If you compare the 2 backups, notice how much area the additional 709 MB requires (difference between XDG2 and XGD3 images).
Cheaper, lower-grade discs have greater areas of inconsistent dye at the outer tracks than higher-grade discs, such as Verbatim do. This isn't an opinion; it's not debatable; it's a fact so live with it. This is why c4eva has reported that only Verbatim discs have been burning consistently error-free. The statement, "But, my cheaper discs have always worked fine," is irrelevant as you will be burning them with a capacity they were never designed for. Don't be a cheap ass and use 6x-8x Verbatims (These will be MKM003's though you will be burning at 4x)
For those of you who wonder why bother with a Burner Max drive for XGD3 games when they have been working fine so far: let's hold a contest to see who can guess the exact number of new security checks that fit inside the 191 MB getting truncated by not using one. The winner gets a freshly-banned console as well as discs that no longer boot; the runner-up gets a profile that's suspended until 12/31/9999 and a pile of coasters.
