Fake Princo 16x DVD-R
 

This is one of the more interesting media offered in today's very limited optical media market.
It is a fake Princo DVD-R media, fake and interesting for three reasons. :) It is not made by Princo, which hasn't been making optical media for a few years, nor by Umedisc, which bought the Princo technology and trademark and offers "official" Princo media. It is made by one of the few remaining smaller and (as yet unknown to me) Chinese manufacturers.
Secondly, it doesn't even have a Princo MID code, but a fake Mitsubishi Chemicals code.
Third, it's not even just a DVD-R, but a DVD+R. :)

I'm attaching an informative test on a drive that is not ideal for testing, but 10+ years ago, when I was heavily into CD and DVD media testing, it gave at least very roughly comparable results to Benq and Plextor drives.
I have the drives to test (Benq, Plextor, LiteON), but I can't find an IDE/SATA to USB converter at the moment. If I find one, I will complete the tests with a proper drive.

The data was burned with the same drive (Lite-On eNAU608 5 CL02) at 8x speed.

Knowing life, the Chinese Princo CD-R is also a fake

Almost certainly. Maybe I'll order them and take a look at them.
