Current system:

Motherboard: Gigabyte P55A-UD3
HD: Samsung spinpoint
OS: Windows 7 64-bit home premium

Planned addition:
SSD: Crucial MX100 256gb

I’m currently running a system with a Gigabyte P55A-UD3 motherboard windows 7 and a regular HDD in IDE mode. I just bought a Crucial MX100 256gb with the intention to format everything and have my OS+programs on my SSD then use the HDD for regular storage.

My motherboard is quite old and features six sata 2(intel) ports and two sata 3 Marvell 9128 ports(aka ”gsata”). Before I formatted everything I figured I might as well test my SSD a bit to see how it’s performing using the AS SSD benchmark tool. (I had to run my OS in safe mode to bench using my sata 2 ports since my OS won’t load in ahci mode cause it’s installed in IDE mode). I used this youtube clip as a reference point for perfomance: http://youtu.be/584z8Wkjqx4?t=4m9s .

Unfortunately I got way less performance than in the video and surprisingly I got similiar or even better performance from my intel sata 2 ports than my marvel sata 3 ports. After searching some on the Internet it seems to be a common problem (http://www.tomshardware.co.uk/forum/277988-32-mushkin-marvell-9128-sata-controller-sata-speeds , http://forum.crucial.com/t5/Solid-State-Drives-SSD/Gigabyte-motherboard-GA-P55A-UD-3-Crucial-M4-SSD-Hardware-and/td-p/68525 , http://forum.giga-byte.co.uk/index.php?topic=6585.0 )

Can I do anything about my sata 3 performance or should I just stick to sata 2? Can I update some drivers or something, and how and when should I do that if I reformat? Also, do the SSD at least perform as expected on the sata 2 ports?

Other tips and tricks before i reformat and install w7 on my SDD using a USB-stick with windows on it would also be appreciated I guess. Not sure which drivers I should download, link to my motherboards drivers can be found here: http://www.gigabyte.us/products/product-page.aspx?pid=3242#dl . Just choose windows 7 64-bit and drivers.
