After buing a new S-ATA disk and running some becnhmarks I though it
was slow, and also I had stuttering problem during disk access, and I
started to look for a newer Promise FastTrak 376 driver for my P4PE.
The results are shocking. The Asus recommended driver seems to be
"capped" in some way, never getting more than 14MB/sec all the way
across the disk (SiSoft Sandra showed a 100% flat graph for it).
With the newer drivers the speed was much higher and decreased as the
test moved closer to the end of the disk - just as all other disks.
Also Windows and programs load faster, so it is a real difference:
