Raid0 Sata SSD's Performance on Z170X-UD3

[motorpsycho]

Hi! Im from Argentina, recently i got a Z170X-UD3 with 6600k processor, im moving from Z77
I am using the same Raid0 i always do, it boot right up out of the box and then i install all drivers with DVD xpress install

But i noticed the raid performance drop by its half, later (on z77) was nearly 1Gb/s Read and 350Mb/s Write, and now is 550Mb/s Read 110Mb/s Write -.-

Im using cristal diskmark

I always assume people will do what I would, and perform a fresh install of windows on a new MB.  I can't tell from your post if you did that?  While you might be able to migrate an install from z77 to z170, each situation can yield different results, and there is no guarantee you will get the same performance after this type of migration. 

Can you tell us more about your OS / hardware?
Types of disks?
Did you perform a fresh install?
OS you are running?
