Can someone explain these Samsung 850 EVO stats?

[Arjunny]

I recently purchased the Samsung SSD 850 EVO 120GB and figured out how to install the drive for maximum performance. I actually ended up buying a new mobo which had SATA 3 and then setup AHCI in BIOS. All this to maximize my drive performance. Here is a screen capture of my SSD Drive stats. I am not sure if the read and write speeds at the bottom are correct though?

Could someone please take a quick look and explain if these speeds are correct?

As I understand it, there will be a new release of Samsung Magician due later this month; re-test when the new version is released, don't trust the current version (especialy for firmware updates!).
