Setting up RAID on an already running machine

Hello there,
I currently have a 500gb HDD which contains my OS and all of my games from steam. In addition to that I have a 1tb drive I use for media.
I got a really good deal on a pair of 256gb SSD's, and was wondering how to set raid up without deleting any content, if possible. I'd like the 2 ssd's to be in RAID 0, with the 1tb by itself for use with media. I do plan on mirroring the 500gb drive (not nearly full) to the RAID'ed (two drives in RAID) ssd's.
The motherboard I have is a MSI Z87-G45, and while I know it supports raid, from poking around in the UEFI I have no idea how to set it up. So i guess the TL;DR on this post would be, how to set up RAID without destroying any of my current data?
Thanks in advance.

That does not answer my question; I got a deal on two drives so it's my only choice to get to the size I want. Unless, of course, you are saying I'm better off getting rid of those two drives and buying a bigger one, which I'm not really willing to do.

Get the two drives. Just use them as two independent drives.
RAID 0 with SSD's gives no performance benefit, and increases the fail potential.

Okay; that makes more sense. Thank you!

You cannot create a RAID0 volume without wiping all drives involved (ie. the 2 SSD's). Maybe I'm reading incorrectly but the 2 SSD's you plan to put in RAID0 are new... so why are you concerned about wiping any data on them?

Your solution would be putting the 2 SSD's into RAID0 as planned then use something like Clonezilla to clone the 500GB HDD onto the newly created 500GB RAID0 volume.

EDIT:
Or use them separately ^^
Far easier solution assuming your current OS drive has less then 256GB of data on it.
