I did a test to see which of three Macs would format a DVD-RW the fastest. The DVDs formatted were Sony brand using Disk Utility.

I didn't time them, just went by which computer was the fastest. Three computers were a 2.4 Black MacBook with the factory Mat****a drive 2GB ram, Mac Pro 2.8 with the factory Optiarc DVD drive and 2GB ram, iMac 2.2 with default Mat****a drive and 3GB ram.

The Black MacBook was the clear winner. iMac second place.

Anyone have any ideas or observations why? To me it looks like the Mat****a drives are much faster.
