Hi,

Wonder if anyone can help me. I have a SATA-II HDD and my MB is SATA-II compatible. In Device manager the drive does seem to get picked up as SATA-II 3Gbps but it's not actually performing to that spec according to the built-in speed test.

Now I don't expect to get 3Gbps but come on surely this isn't right?

The drive is (as shown in screenshot) a Maxtor Diomandmax 10 6V300F0. The MB is an ASUS M2N-SLi deluxe. I have it plugged into the NVIDIA SATA controller not the JMicron one.

Has anyone else come across this? Is anyone else using this MB? If so could you post with your speed tests please?

Thanks....
 
Can you run hdtune (free version is fine) and screenshot the results?
 
You will see nowhere near SATAII performance because you have mechanical limits on the drive (drive can only go so fast).
 
Thanks for the quick responses - here is the screenshot:

The sudden drop is where Winamp change tracks BTW.

I know what you mean Ockie but I would have expected it to be faster than this though?

There is a jumper on the back set to pins 3-4. I have read that this HDD shouldn't have any jumpers on but I guess it's in the right place as it's being picked up as SATA-II?
 
The interface speed is 3Gbp/s which is about 375MB/s; however, the fastest mechanical Sata II drive on the market can only do ~100MB/s sustained. Your results are perfectly normal for your drive.
