What media code are these

Does anyone know what media code these are and if they burn well at 8x and 12x http://www.newegg.com/Product/Product.asp?Item=N82E16817131594


I haven’t tried them but they should be CMC MAG.M01 or TDK 003.

I was tempted myself but I just had some very good TDK 8X start to produce bad burns in mid stack and I had to drop to 4X.
