I installed Asus U3S6 card (asus says provides a slot SATA3 PCIe4x REAL): http://www.asus.com/Motherboards/U3S6/ [/ URL]

Here is a review:http://ntsblog.homedev.com.au/index.php/2012/02/23/asus-u3s6-review-benchmark-sata-3-add-on-card-sata-ii-onboard/

I updated firmware Samsung 840 Pro 256GB SSD with Samsung Magician. The main drive I use it to boot Windows

I installed the latest drivers from ASUS: [URL="http://support.asus.....n&m=U3S6&os=30

I connect U3S6 in PCIe4x slot (not the 16x which is the VGA) and Samsung 840 Pro 256GB SDD on U3S6

I have enabled AHCI in the BIOS

HE SSD optimized using this guide: http://www.thessdrev...dows-8-edition/

This is my speed tests:

far away from reading and writing 520MB supose speed...
Anyone know how to fix it?

Here they say not to use Marvell drivers and use SATA standard. What do you think? How Do I?

I would recommend using the SSD without the add-on card, normal SATA II ports from Intel will provide more performance then the plugged in controller.
This should be something for you:
