The german computer magazine "c't" has a test on 4x media in the newest issue. The interesting thing is that
all 4x plus-media they tested (except Verbatim) were RICOHJPN. They tested Maxell, Memorex, Philips, Platinum, Ricoh, Speer data and TDK. This reflects the situation in Germany- things may differ in North America. Chances are good, though, that any 4x plus-media comes from Ricoh.
The quality was good. Scans by Audiodev (at 1x on their reference drive) showed max. PI Sum 8 values of <67, much lower (<10) for most of each disc (the norm requires a maximum < 280). The minus-media they tested had significantly higher values, up to 636 for Nanya media!
Incidentally, the newer versions of KProbe can sum the errors over a varying no. of samples, so that PI Sum 8 can be shown directly (but cfitz mentioned that already). The values depend on the drive and scan speed, of course. In particular, scans done at 8x or 16x will probably show larger PI counts than the Audiodev scans and may exceed the limit.
aviationwiz- if you save KProbe scans as PNG's instead of jpeg, they'll be smaller and better quality (win-win situation).
