To be sure I checked my manual to be sure it was a native port, but it really didn't say if it was native or not, so to be sure I looked it up and came upon, an extremeoverclocking.com forum topic, which can be found here
, and sure enough it confirmed that I was using the native port.
First, to clarify regarding "native" SATA/USB ports. Native = port directly connected to MB chipset. It's a "built in", supported feature so no additional 3rd party controllers are necessary. A user manual almost certainly won't use the term "native", but instead will reference the chipset (or a controller for OEM added, "non-native" ports). I went to the Asus Crosshair Formula IV product page and downloaded the manual. See the two screen shots form the manual below. The right image expressly states that there are six "native" SATA 6GB/s ports for the AMD SB7850 chipset - all colored in RED. There is one SATA 3GB/s port in BLACK connected to a JMicron controller which you mention.
You want the SSD (and any other hard drives) connected to one of the six RED SATA 6GB/s ports. It seems like that's the case, but you say "the
native 6GB/s port" so I want to make sure everything correctly connected. FYI, do not use the single BLACK SATA port until the others are filled up, and if needed, connect it to a DVD/BD drive first. The JMIcron controller SATA port will be noticeably slower than any of the native SB850 ports, even if it was a "SATA 6GB/s" port rather than SATA 3GB/s port. I'm sure you are, but take a minute to verify you are using a SATA 6GB/s cable as well.
If you have not done so, the FIRST thing you need to do is go to the link I provided above and read the sticky threads on optimizing SSDs for Windows 7. It does
make a difference! After that, check to see that NCQ is enabled/working. It should be, but make sure. What ACHI driver are you using? MS Win 7 or AMD? If your installed the AMD ACHI driver, try rolling back to the latest MS Win 7 driver. If you did not install the AMD ACHI driver, download the latest version from AMD website directly (not Asus) and install that. Also, see if there's a a firmware updated for your SSD. If it might fix something related to AMD chipsets, etc.
A thread here
(same chiipset, different OEM & SSD though) mentions checking bios setting for SATA III support enabling, and possibly toggling the setting as a fix. Not sure if you have the same type of bios setting on your Asus board. Lastly, it's a new SSD so consider calling Mushkin product support. They may have some more ideas.
