|Thanks Lurkwithin for helping.|
I understand what you are saying, and if I was reading this I'd agree completely. HOWEVER :) things aren't always what they seem.
I've just timed how long it takes to transfer a 3.02GB file from one Sata II drive to the other Sata II drive - I specify drives, not partitions; 32 secs. That to me would be SATA II speed.
I know 300 mb/s is the theoretical speed for Sata II, so I did a benchmark on Sisoft Sandra Lite under Physical Discs. The drive index for my C drive Sata II disc was 83 mb/s, whilst the other Sata II drive came in at 94 mb/s. In the comparison graph, both results beat the closest reading within the Sisoft reference program:
WD Sata 150, 3.5", 10 RPM, NCQ, 16mb Cache,x64 - 67.1 mb/s
2 x WD WD5000 500GB RAID 1, SATA 300, 7200 RPM, NCQ, 16mb cache, x64 - 60.339 mb/s
Seagate Barracuda 7200.10 320 GB Sata 300, 7200 RPM, 16mb Cache, x64, 61.225 mb/s
Hence, I feel that the speed is indeed there! I just can't understand how this is happening.
Here is a link to my motherboard with spec sheet:
Now interestingly, here is the spec sheet to my other PC which I am typing this on, and I use for general PC work:
I installed XP 32 bit on this machine, also on a Sata II drive, and also without having to install any drivers with F6. However, on this machine, under the IDE/ATAPI settings in device manager, I see Nvidia NForce Serial ATA controllers......
Could it be a difference in the chipset on the latter machine being northbridge/southbridge (NVIDIA GeForce 6150SE / nForce 430), where as on the machine I am concerned about, there is only one chipset, the Nivdia Geforce 8200?
Thanks for persevering by the way - I feel I'm going mad!
