I have IRST running on a pre-built machine and love it... I want to build another utilizing IRST.

I want to use a 250GB SSD (64 for IRST) with a 4TB HDD.

I'd like to use the 64GB to accelerate the 4TB, and use the remaining 186GB for the OS (WIN 7 or 10)

Is this possible? Are there any insights/recommendations/limitations to this? For example, I figured I would configure BIOS, install OS to HDD, install IRST to partition SSD, then re-install OS on remaining SSD space.

If this isn't possible I will bite the bullet and just use a 2nd SSD.

Parts being used for setup:

ASUS LGA1151 DDR4 H170 ATX Motherboard H170

Intel Boxed Core I5-6500 FC-LGA14C 3.20 Ghz 6 M Processor Cache 4 LGA 1151 BX80662I56500

Samsung 850 EVO 250GB 2.5-Inch SATA III Internal SSD (MZ-75E250B/AM)

WD Blue 4TB Desktop Hard Disk Drive - 5400 RPM SATA 6 Gb/s 64MB Cache 3.5 Inch - WD40EZRZ

Windows 7 OEM or 10 OEM (haven't decided)

Thanks!
