What should I do? Is it even possible to set the ssd's as RAID? I'm kinda new to this whole thing. I do appreciate your patience and help.
While possible to RAID 0 the two SSDs it is not a good choice IMO. If you do decide to stick with the RAID, you need to set it up in the bios and have the driver to install at the beginning of the Windows install.
My preference would be to install the OS one one drive using AHCI mode, and use the second as a program drive.
