I've probably bought 20 of the NEC 2500's and never a problem. I just started buying the 3500's just for the faster CD-r writing. In about 2 years I guess we'll see 16x DVD media.
i've been using Be-All media and burning @ 12x with no problems on the drive, It isnt 3 times faster than 4x though, takes about 9.5 minutes compared to 14.5 @ 4x.
I dont care about 16x media, Just give me some cheap 8.5 DL disks!!!! This is BS $10 a disk!!! for a DL
