Say I install my OS on Samsung 850 or 750 EVO and if I use PCI-e SSD as secondary HDD and install my 2 or 3 fav games on it , will I be able to leverage or use the 2000mbps reads / 900mbps writes OR does my OS SSD causes bottle neck since it has max of 550 MBPS?

Your gaming performance will not be impacted whichever way you do it.

Can your Z87 boot from that PCI-E? Maybe, maybe not. You'll have to delve into the user manual to see.

What ever is read off the SATA drive will be read at SATA speed
Whatever is read off the PCI-E drive will be read at that speed.

One will not "bottleneck" the other.


Further, why are you wasting money on a PCI-E drive for games? Highly unlikely you'd see any difference in actual use.

I think I confused you , 850 / 750 EVO's speed caps are around 500 Mb/s.
But PCI-E SSD Speeds are 2000 Mb/s Read and write around 600Mb/s.

The problem hers is I have a mSI-GD65 Z87 MOBO which dont have M.2 SSD slot , so If I setup SSD as primary and use PCI-E for gaming will I be able to use full potential of PCI-E SSD read write speeds ?

I read that it will be difficult to use PCI-E as OS Primary Drive on Z87 MOBOS since the BIOS wont recognize this SSD's ?

Also practically will there be significant noticeable performance seen ?

Everything runs from the RAM or GPU when your game is running. Some games will load new levels from the HDD (in your case your PCI-e SSD) but the Samsung wont be used even though windows is installed on it. I personally would install the games onto your best performing drive.
