I just ran some FE/FT tests on Fuji 8X (Yuden T02), Verbatim 12X (MCC 003) and Verbatim 16X (MCC 004) discs. The tests were conducted on a PX-716SA using Plex tools version 2.20.Three disks were taken randomly from each stack. All Verbatim, 12X and 16X, indicated they could be burned at rated speed. None of the Fuji (Yuden T02) indicated that they could be burned at their rated speed.
I have read that Taiyo Yuden will often sell discs that are not top quality to other vendors. This test, at least for me, would appear to validate that information. I would like to hear results of other FE/FT tests that were conducted on media that has a Taiyo Yuden media code. I am curious to see if a FE/FT test will display distinctions between media sold with a Taiyo Yuden brand and media sold with other brand names that have a Taiyo Yuden media code.
