Samsung 840 256GB Pro: IOPS? Why so low? - Page 3

Green = DXM04B0Q Firmware
light blue = DXM05B0Q Firmware right after the update
Blue = DXM05B0Q after disabling LPM and (if it matters in any way) C1E

Samsung, if you want to keep f*cking up people's SSD's, at least implement a downgrade tool or procedure.

Hi! I have not understood if you managed to downgrade your firmware, to test the older and the newer one. I would like to know it because I have the same problem... thanks

And Intel drivers have higher multi-threaded performance than the default Microsoft drivers.

You can see this for example by comparing OmegaStageThr33 AS-SSD results (using msahci) with Travisimo values (iaStorA).

Just go into device manager and update INTEL *whatever here* SATA AHCI CONTROLLER with the driver you downloaded
