As we can see from above, the performance of the 6416 and 4416 are almost identical. Also, even though the drives are rated at 16X, the benchmarks show that the drives perform consistently higher with an extra of almost 170 Kb/s. Not bad indeed!

Earlier on, I've explained that the reflectivity of CD-R media are generally lower. Most of us including myself, believe that due to the lower reflectivity, accessing a CD-R media will be slower than accessing a factory-pressed CD. I did a benchmark on CD-R media vs factory-pressed CD and I was surprised that the results are almost identical.

6X Writing
The sweet spot about the 6416 is the 6X writing capability. I must admit I was Woohoos <tm> by the speed of the drive. Previously on the 4416, I was staring at the dialog box of Adaptec EasyCD Creator which displays a constant 600 kb/s being burned onto the CD. But now, I'm seeing a consistent 1 Mb/s burn speed, that's even higher than the 6x (900kb/s) rating!

From the above, you can see that the new 6416 is 50% faster than the previous speed champion, the Yamaha 4416. The time was measured the moment the READ/WRITE LED started to light up till the time the disc tray popped out.
