To get full SSD performance you have to install Intel drivers and get rid of Microsoft Standard AHCI driver.
You will find them here: Intel AHCI for C602 – RSTe_and_AHCI_Drivers_GUI_CIM_CLI_3.8.0.1111_2013.10.03

To also get rid of “SAS Controller” driver not found in Device Manager, install SCU driver.

For both I used Windows 8 / 2012 x64 driver.

To get rid from driver not found for serial controller, deactivate Intel AMT in Bios setup.
