I did some tests using ATTO to check if upgrading the firmware/drivers on my SX6000 would speed up thing. The answer is yes! It improved the write speed a lot (700%) for small blocks and quite a bit (50%) for large one. The read situation improved a bit but not as dramatically as for the write. This upgrade is advised!
