Solid State Drives (SSD)

[sanic]

Hello,

sorry my english is unfortunately not so good.

My new C300 256GB arrived a few days ago; it's been hooked up to the sata3 ports of my X58A Gigabyte UD7.

Most benchmarks are great and within expectations, but there seems to be a problem with PC Mark Vantage:

Please notice the red marked area on this screenshot:

as you can see, the result #7 is way to low. The summarized total is therefore low as well.

If i connect the drive to the onboard ICH10 sata2 controller, everything is fine including Vantage.

Can somebody explain that to me? Thanks anyway.

I'm not sure I understand your situation sanic.

You say in your post : "If i connect the drive to the onboard ICH10 sata2 controller, everything is fine including Vantage."

This leads me to believe your using an addon controller.

If it is a sata 6GB/s something is wrong for sure.

You may need to change your slot choice on the motherboard.

I ran PCMark before and have a picture of it below...

Once it is ok for viewing, you can use it as a comparison.

I put my SATA 6GB/s into a pci-e x16 slot and resolved my slow down issues.

My PCI-e x1 2.0 slots seem to be messed up.

Good luck with your problem sanic, I hope it is as simple as a slot change, as it was in my case.

But I do not use any additional card. The SATA 3 ports mounted in the gigabyte UD7.

Here is what, what I found

"For today’s tests we went back to the ASUS P6T7 WS SuperComputer for all but the SATA 6G C300 benchmarks. While testing the GIGABYTE X58A-UD7, we found an issue that effects solid state drives on this board. In our first chart of the C300 we noticed that one test in PC Mark Vantage ran extremely slow. At the time we wrote it off as an issue with the C300’s firmware, but further testing exonerated the C300 as the cause. A big thanks goes out to Olin from Benchmark Reviews for helping us with re-testing. GIGABYTE is currently investigating the issue that seems to affect the C300, Indilinx Barefoot and X25-M in this one test"
