6GB interface with WD1002FAEX and GA-X58A-UD3R not working


Aug 6, 2010

I recently bought the products below:

WD1002FAEX -- 2x1TB:

Gigabyte GA-X58A-UD3R

Sata 3 cables:


I set up the HD in Raid 1 because the Motherboard said:

Marvell 9128 chip:
2 x SATA 6Gb/s connectors (GSATA3_6, GSATA3_7) supporting up to 2 SATA 6Gb/s devices

That worked fine, b/c I see it using the Marvell control panel in the browser and in my bios.

However, that same CP told me it was running in 3GB speeds, not 6GB as it should. I'm using Sata3 cables and connected both HD using the Sata 3 ports on 6 and 7.... so it should work, right?

In my Bios I have these settings:

ICH Sata Control Mode -- RAID (XHD)

GSata 6_7/IDE Controller -- Enabled

GSata 6_7/IDE Ctrl Mode -- AHCI (also give the option for IDE or Raid)

Sata 3 Firmware Selection -- Auto ("chip" uses the firmware on sata3 chip, "auto" uses the firmware with the one embedded in system bios. Do nothing if on chip firmware is newer)

When I see the Marvel Raid thing in the bios I see the PCIe Speed rate is 5.0Gbps. But when I go to each individual drive it says "Current Speed: 3G".

I think before I set it up in raid I installed in manually and the speed was 3G.

Please advise how I can get the 6GB interface. Thanks.
All I can say is that for hard drives the fact that you're using a 3GBit/sec connection is irrelevant. The drives themselves can't transfer data at more than perhaps 150MByte/sec, so the 3Gbit/sec speed is perfectly adequate. A 6GBit/sec connection isn't going to make them any faster.
