OK, so here was the problem:
Using DVD Shrink 3.2, I re-authored and then backed up a DVD Movie from a Maxtor Maxline III 16MB cache 300G HD to a WD 36G Raptor. This process
took 3 minutes and 58 seconds and averaged 29.5KB/s (that would be 29 Megabytes a second).
I thought, wow, these SATA drives are more or less the best you can buy short of SCSI, why am I only getting 29MB/s ? So, I tried the same process on my Intel rig (ASUS P5WD2/P4 640/955x chipset). The result? 1 minute 45 seconds elapsed time and 47MB/s. That's more like it, but damn, what's wrong with the AMD rig?
Solution: remove the crap NVIDIA IDE Drivers
Result: elapsed time 1 minute 20 seconds, a whopping 54MB/s :woot:
I suppose that the NVIDIA IDE drivers are CPU bound or just plain buggy. In any case how could they have missed such a disparity in performance?
So I'm a happy camper running the standard issue MS XP64 IDE controller drivers.
