well, I've used 3 different software programs for recording.
Nero (which came with the drive)
Roxio Easy CD Creator 5
Cdrecord (Linux software)
With Roxio and Cdrecord, they both tell you what the current speed is. Roxio tends to display around 8x - 10x. Cdrecord displays 15x. Plus, both of these display the time it took to record the cd-r. Comparing this time with the time it took Nero tells me that Nero is even recording at the same speed. So, overall, I'm getting only 15x MAX speed.
