Here are a load of kprobe scans for various media / various speeds. The firmware is unhacked 1.10 and the PC is a P4 2.6HT, 1Gb RAM, 250Gb HDisk, ATI Radeon 9600XT.
My overall impression is much better than the LiteOn 411 which I used for the scans. It seems to be quite picky with the media but it is very consistent (always burns bad with certain media, always burns good with others). The LiteOn was very inconsistent sometime burning good sometimes bad even with the same media batch.
I’ve got some Verbatim DVD+R 8x on the way and will post these results when they show up!!!
