I know both disks are near perfect, assumming the peaks are equal and very constant, technically which disk is better. ie PI or PIF is more important?

# Us0n Pi/pif-10000/200, Vs04 Pi/pif-5000/500

Hi

Neither nor. Both disks have too high PI/PO and thus are crappy and I dont think it is readable is it?

Sorry for the confusion both disks are near perfect, the numbers there are the SUM. The average number should be US0N - 1.xx/0.002, and VS04 - 0.xx/0.005

OK, to make my question simpler, 2*pi/pif and pi/2*pif , which is better disk (assuming peaks are equal and the errors spread evenly)

2 pi, because pif is ( i reckon) failures that cant be corrected by the drive. But 2 pif is awesome. You shouldnt be having any problems with that disc
