Do you own a computer with an Intel chipset? If you do, you probably need to make sure you are running Intel’s Rapid Store Technology to make sure the appropriate drivers are installed. By loading the drivers, I saw a 48% increase in performance and a 43% increase in performance (Random read and random write)
Note: Even with Samsung’s Magician, drive operations was slower than normal.
