Hi, I am in the process of upgrading the storage on my computer. I just bought 2 Samsung SSD 840 Pros with the intention of creating a Raid 0. Before installing everything I referenced my motherboard's manual to see how it's done (the motherboard does support Raid 0 configurations). The motherboard is a Gigabyte 990FXA-UD3. However while going through the steps I noticed one of them gives an option to clear the MBR. My first thought was to ignore this step and not clear the MBR. However, I'm not an expert on the subject, therefore I am not entirely sure what to do. I skimmed the forums trying to find a thread with this same question or one close to it, but could not find anything. Thus, my question is, should I clear the MBR or not? In addition, because I just bought these SSD's I have no data on them.

I have to sandisk 256gb ultra in raid 0 and I only stor games one it so far It isn't causing any pb. games load fast an there is no issue. but I do not know the steps for your motherboard: if you should or should not clear the mbr. maybe download the uefi bios first with an old hard drive than try the steps in the video.
I'm going to be obnoxious and put my two cents worth in. Unless you want to do it to see what happens, don't put them in RAID 0. The improvement will be noticeable only if you are benchmarking, the risk of failure is increased. Experimenting is a great reason to try this, but not on any system that you want to be reliable and recoverable.

are the steps as followed in the bios section change sata configuration from achi to raid mode than exit bios while saving changes than the system will reboot itself and the screen will show you the hard drives that you have and what kind of raid you want and then the size of the raid. that is all you should be seeing.
 
^5 +1 what WyomingKnott said.

For all practical purposes there no reason for consumers to use ssd's in a RAID array anymore. The exceptions would be personal experimentation and highly complex professional work that boggles the imagination.

Tom's Hardware and other sites have conducted extensive testing and comparisons of a single ssd's versus multiple ssd's in a RAID array. The results were pretty much unanimous. Here is a link to the article published by Tom's Hardware:

I appreciate the feedback, and I am familiar with that article, however I still would like the try the Raid 0. I like to think of myself as a small time computer enthusiast, therefore the idea of twice the read and write speed is appealing to me.
 
Great! Experimenting is fun. I've done my share of experiments over the years. About 4 or 5 years ago I turned my mid-tower case upside down and placed it on four soup cans and took cpu core temperature readings in response to a spirited thread about cpu cooling and hot air rising. The discussion had failed to factor in forced air systems. When I posted a photo of the experiment some of the forum members joked about the soup cans but they got the point.

Good Luck!
