AMD to Release NVMe RAID Support for X399 September 25th
More news coming AMD is that the X399 motherboards will be supporting Bootable NVME RAID. A nice free upgrade I'd say. AMD got some heat recently, not having this feature available.
So to hook into that last topic, the feature was not available just yet. AMD will be releasing a free NVMe driver for the X399 platform. The new driver will enabled RAID 0, 1 and 10 with up-to 10 devices. If you wanted to RAID three M2 SSDs, now you can. You could in theory also add M2 SSDs on a PCI-Express add-in card and have these join the RAID group. It is not yet known if the feature is a chipset function or a software based solution.
The good news is that the new RAID driver is bootable. This however will require a BIOS update. The driver and BIOS updates should become available starting September 25th.

And there in lies the crux of the matter there isn't an M.2 slot on the Asus CrossHair V Formula so RAID0 is it for speed or find an bootable PCIe SSD card but I'm not interested in paying out the several hundred bucks they want for them here

I was referring to if/when you get a X399 board.
But in your case, you can still get a PCIe to M.2 card - they're not expensive. Or, just a straight-up PCIe SSD.
As for your current setup, you'e going to lose more performance in the long run if you don't have TRIM enabled. Also keep in mind - you lose time during boot due to the RAID controller initializing. If the only reason you're using firmware RAID instead of software is because of boot speeds, well, you haven't really gained anything. Use a single drive for boot, use software RAID for your SSDs, and you'll get the best of both worlds.

I can see why you might see a performance increase booting SATA SSDs via RAID0. Depending on your configuration (SATA controller, the drives, the block size, the filesystem, OS, etc) you can get better performance when RAID'ing an SSD, but in most cases you don't. I'm pretty confident you won't notice a performance difference with M.2. In fact, I bet you'd lose performance.
