Seagate sata 3

Does your computer support SATA III 6G? Only the very newest machines do?? Did you buy an new SATA III Card?

Your machine SPECs only show support for SATA II 3G.

The Asus board I have supports Sata 3...Asus P6X58D..also the Rampage extreme 3,new gigabyte UD9 i think does also.
So yes the newest on market and top end at that have it.

According to Asus' web site the motherboard you have listed only supports SATA II 3G. I am not trying to upset you I am just trying to point out that if your motherboard only supports SATA II 3G then installing a SATA III 6G hard drive will NOT gain any performance because the motherboard does not support it. I just want your tests to be fair and make sure that you are testing a drive in a way that will truly show its performance.

@ simmo, If you look at my screen shot I think you may be confusing SATA 3 Gb/s with SATA III they are not the same thing.

Well do not waist your time with the sata 3! It does not appear faster or worth the money. I found one miss priced and decided to try it. HDtune did not impress me with the results.

FYI: No single mechanical harddisk can use 100% of SATA II 3Gb/s bandwidth, thus with SATA III 6Gb/s, you won't get any performance increase AT ALL. It's mechanical limitation, you can only spin the disk that fast, faster will yield mis-read/writes. If you want to get the speed, use a SATA III 6Gb/s SSD, or connect a SATA III 6Gb/s port to a compatible SATA multiplier, and use 4+ harddisk using 1 SATA port.

What you see in your test is the characteristic of a mechanical HDD, nothing new...

+1 to that.

It's unfortunate though how many people don't realize these facts and go ahead with hardware purchases thinking it will yield a good difference.

According to NewEgg the Asus P6X58D supports Sata 6.0Gbps

Although, as stated above, the drive simply won't perform any better since it wasn't even maxing out the SATA 3.0Gbps interface.

The OP Motherboard is a P6T58 not a P6X58:

My board supports SATA III 6g, but as of right now, it isn't being used. Still waiting for prices to come down and more product selection.

Same here, Afraid it will be next year
