I am an IT Professional by trade, so I have quite a few PCs to play with. I have noticed that the time it takes to clone the same DVD differs wildly (2-3 fold) between rigs. But here is the catch: the faster PCs are not the fastest at making DVD backups. A 915 chipset with a 3.4GHZ HT P4 beats a new 965 chipset running an E6600 CPU. Both have high end ram, and plextor drives. An AMD x2 rig falls somewhere between these two. So the oldest technology makes clones in about 18MIN while the new conroe technology takes about 35MIN on average for the same film. All IDE and SATA modes have been checked and double checked. All firmware (MB and DRIVES) are up to date. All other benchmarks run faster on the conroe rig. So my question is, what hardware does slysoft do their development and testing on? It would be interesting to compare notes.
