AMD old SB 7xx chipsets ■■■■ for SSD performance
Often the windows generic is better. Otherwise, backtroll to the vista driver, which performs better. Going to the Vista driver has one advantage: performances go up. Howrever, you often loose the smart data reading since it considers your controller as raid.
Benchmark shold be done as a secondary drive unit, or with all antivirus off, and with minimum services running in the background. Your sequential numbers look ok anbd these variatons are likely due to antivirus/services interfering, but where you will see a big difference regarding the driver for the SB controller, are the 4K results
