ND-4570A/71A - DVD-RAM performance

Does anyone have a handle on what the real-world DVD-RAM performanc is like on these drives (with write verification enabled). Is it 1-2.5x or can it get close to 5 even with verification?

It can burn max 5x, with verify enabled it needs the double time normally.

Ok, I’ve seen/guessed that from the spec, just wondered if anyone had any real-world measurements

Check the blank media section, there are screenshots and tests.
