Hey guys! 

I really want to setup raid on my HDDs and was wondering how to do it with this motherboard: https://us.msi.com/Mother ... l#hero-specification

I want to setup the raid that makes write speed super fast. I think its RAID 0

Do I need to buy a part?

Intel Rapid Storage Technology Driver \ It is in the driver section of that motherboards downloads. The instructions are in appendex b in your motherboard user manual. You need 2 hard drives or 2 ssd. They don't have to be the same size, or speed for that matter. but just like sli or crossfire the lower speed and size traits will prevail. It works best with identical parts.

I agree, they don't NEED to be identical side and speeds. However, it is advisable for them to be the same size and speed.

RAID 0 is not a "true" RAID because there is no redundancy. In fact, you are increasing chance of losing data due to drive failure because EITHER drive 1 OR drive 2 can fail in order for you to lose all of the data.

That being said, the read/write performance will be close to 2x (not quite 2x) with RAID 0 compared to what one of those drives will be capable of. RAID 0 on HDDs will not be too beneficial for you. If you absolutely want to do RAID 0, I would suggest doing it on 2 SSDs.

However, further to that point, RAID 0 on 2 conventional SSDs is still much slower than PCIe (or M.2) SSDs. Typically, with conventional SATA 6G SSDs, you are limited by the SATA 6G speeds, so at most you will get around 520 MB/s sequential. With PCIe / M.2 / NVMe SSDs, you sequential read speeds can be up to 2,500 MB/s and sequential writes can be up to 1,500 MB/s. Obviously, this is MUCH faster than RAID 0 conventional SSD pairs.

Then, we go onto RAM drives, where you are only limited by the speed of your RAM. Faster the RAM, the faster your RAM drive will operate. You could have a 30GB RAM drive that could run at 12,000 MB/s (however they are VERY expensive).

Is it possible to have 2 different raids on the same system?

Also, with my motherboard manual it says that sata port 5 and 6 will be unavailable while using M.2 so does that mean I have to disconnect my disk drive? I have 2 SSDs and 2 HDDs already connected. In my manual, it says it in page 104.

It should be possible to have 2 different RAIDs.

Port 5 and 6 are SATA Express ports. So, they use a few lanes from your available PCIe lanes. We had a conversation on this the other day how the 4790K only has 16 PCIe lanes. So sometimes they have to share. By share, I mean you get M.2 or Sata Express, one or the other. 

You can move your drives to SATA port 1, 2, 3, and 4. If you have a CD drive, you can just remove it. No one uses it anymore anyways. This is only required if you plan on buying an M.2 SSD. Otherwise, leave it as is.

As UrbanCamper pointed out, Appendix B is your friend when it comes to RAID related activities on the motherboard. 

In my opinion thought, I would stay away from RAID 0. You should be adding redundancy, not going the other way for a small amount of performance gains.

I need to go to the gym, sadly I am too skinny to care

No gym at your college?

Absolutly, too bad thats a drive. But worth it

Long enough to go to the gym though.

Having a 2 hour break between classes kinda blows. Too short to go home, too long to stay entertained.

Also, the PVP aspect of it is really fun. It is comparable to Quake and Unreal Tournament.

If we keep growing we are planning on adding fireteam channels under the Destiny 2 channel so it isn't so crazy in the main channel.

I mean, I personally enjoy it. We have a pretty active crew (2-4) people who log in every day that can help you out if you have any questions.
