Until very recently, BTC did not list any media as compatible at 8X. Now, they show only TUDEN000T01 and DAXON AZ1 as being 8X capable. While Plextor and others will write some 4X media at 8X, apparently the BTC will not.
During the period of time that BTC did not list any compatible 8X media, I kind of felt that I had bought a 4X drive with false speed rating.
Now, I have to find either TUDEN000T01 or DAXON AZ1 blanks to see how it does perform as an 8X writer.
That being said, I've been very pleased with it's performace as a 4X writer. I've successfully used it with both + and + media, though it does seem to be a bit faster with 4X - discs. It takes a tad longer to recognize the +R media. Both play flawlessly on all stand-alones I've tried them with. :rolleyes:
