How much Jitter is bad
How much Pif is bad
How much Pof is bad
And if this is a good or bad disk
And why does it test at only 1x?

Well you need to upgrade with the latest firmware B7M9 for testing up 1x. Any PO or POF is bad that’s uncorrectable errors and means it’s probably unreadable. PI (top graph) should stay under 100 and PIF (bottom graph) should stay under 16 or 10 , I’ve heard both. The PIF graph is probably the most important. There’s better explanation somewhere else in this site. And jitter I don’t know.
