Poor Write rates on ssd

[brookejp]

Hi Guys got a Asus P9x79 Pro M/B and a Samsung 840 Pro SSD as you can see the read speed for the ssd are well into advertised speed but the write speed is appauling..any idea would help, I do have the ssd plugged into the Intel x79 Sata 6 port.

Thanks

Sorry yes I have optimised the system to the recommended settings via Samsung magician software

test with atto software,i think magician tool optimisation lowers performance
