Corsair Force LS is too slow on MBP Mid 2012

Hi!



Today I bought corsair force ls and replace it with my macbook pro's hdd. I've installed os x and tried to do some speed tests. After test I was very surprised... Test results says that writing speed is 95-100 MB and reading speed is 350-460 MB.



Anyone who knows why is it so slow ? Please help me..



Thanks...
