Motherboard: GIGABYTE GA-X58A-UD3R SATA 6Gb/s, USB 3.0 Intel Motherboard
Hard Drive: Western Digital Caviar Black WD1002FAEX 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5
Cable: OKGEAR 18" SATA 6 Gbps Cable, Backward Compatible with 3 Gbps and 1.5 Gbps

How can I know my hard drive is running at SATA3 instead of SATA2.
I tried both SATA2 and SATA3 ports, but the performance looked no difference.

In the device manger. I didn't see the name of SATA3 controller, Mavell.
I also checked the BIOS, all the SATA controllers are set to Enable.

will I get a higher windows index rating if I use the SATA3?

Thanks for any help!

A hard drive is not fast enough to have any difference in speed between SATA II or III.

CrystalDiskInfo may tell you that. You shouldn't get a higher windows index rating though, and if it does it is artificial. Your HDD is like a cat that can drive 140 km/h max while the speed limit was 300 km/h. Now the speed limit goes up to 600 km/h but your car still has a maximum of 140 km/h.

It really makes no difference. The limit of your disk is around 125-130MB/s.

Try HDTach.
If the burst speed is around 220 MB/s then it should be SATA2, if the Burst speed is around 250-350MB/s then SATA3. If you get a result of around 1000MB/s, the disk cache is messing the test up. Hope that helps.

I am sure I use the right port.

Here is what I got from HDTach test, it looks like that it's running at SATA3.



However, its rating is only 5.9..........compared to my other ratings........sign...


anyone uses this hard drive with SATA3 and gets the similar rating? Thanks!

That is standard. My 500GB Barracudas have similar performance and I get 5.9. The Windows experience Index is not a serious benchmark. It helps sell hardware. You need an SSD drive to get 7 for Primary Hard disk.

Try 3D Mark Vantage for an overall system performance guide.

But it does look like Sata 3.
