I know raid 0 will work fine with 2X SSDs with the same size and sequential Read/Write speed. But if two SSDs have different 4K Random Read/Write, how will it affect performance?
My SSD's 4K Random Read/Write speed:
SSD1 = 94K/75K IOPS
SSD2 = 80K/76K IOPS

I bought a gaming laptop (gigabyte p35x v3), there is two versions of it, one has 4k resolution and 2X 128gb mSATA SSD (in RAID0), but as i dont need 4K i bought the other 1080p version which has only one 128gb SSD and a empty mSATA slot. 128 gb and 320 Mb/s isn't enough for me and therefore i want a raid0 configuration so that i have 256gb and atleast 600 Mb/s as the 4k version has (i want that mostly for faster game loading time)
The only problem is that i cant find a store (in germany) that sells this(SSD1): Liteon LMS-128L9M
And the alternative SSD i'm buying is (SSD2): PLEXTOR PX-128M5M - it has a bit faster sequential read speed. But it's 4K Random Read is 14K IOPS lower and therefore my question is if this will make the raid0 performance worse than if i had two identical SSD's?
