Windows 10 Parity vs RAID 5

[Jebidia]

I see a RAID 5 option in the disk manager in my Windows 10 pro 64bit os but it's greyed out , but I also see if could do a Parity RAID in storage space which it will allow me to do. So I'm curious why RAID 5 is greyed out and is there an advantage to getting RAID 5 to work vs Parity, which I know has horrific write speeds...I don't need a lecture on why I'm choosing RAID 5, just looking for someone with insight to my question.
Thanks!

That file for my mobo contains the attached...not even sure how to install that:

Those are storage controller drivers, they're probably already installed. They would be listed in Device Manager under "Storage Controllers"

Just FYI, I thought I'd try the REFS files system on the parity RAID as I read some said there was a performance bump. Spent about a 1/2 hour and every single time it said a program was accessing the drive and it couldn't complete the action, but with NTFS it went through fine...I rebooted a few times...who know, but I'm leaving it as is and I do appreciate your time.
