I am looking into setting up Raid 0 across 4 Samsung Evo 850 Pro 512 GB SSDs but I have some initial questions.

Q. Fists off, I am using an Asus X99A Deluxe U3.1 motherboard. Are there any complications that anyone knows of when trying to set up Raid 0 with this board?

Q. I am using Windows 8.1 Professional as my OS. Are there any complications that anyone knows of when trying to set up Raid 0 with this OS?

Q. How much total drive storage can Windows 8.1 Pro see?

Q. Has anyone actually or is anyone actively using the exact build that I am planning that could lend me some advice? An Asus X99A Deluxe U3.1 motherboard and 4 Samsung Evo 850 Pro 512 GB SSDs in a raid 0 array?

Q. Would an internal M.2 SSD be faster than a 4 drive raid 0 array or is raid 0 the faster when it comes to transfer speeds/OS boot up time?

Q. One of my 512 GB drives will have Windows 8.1 Pro already installed on it when I am ready to set up RAID 0 in the BIOS. Are there any complications with including the OS drive in the raid array?

As always thank you for any help that you can provide :)

I don't think RAID 0 is going to do what you want.

There might be some gains in I/O speeds, but not as much as you might assume. I do not know the specifics of the SATA controller on the board you are using, but it's almost certainly going to bottleneck.

RAID 0 has no redundancy, if even one drive has a hiccup and drops from the array, all your data is gone. On JBOD, it's only what was on that drive.

While there should not be any issue with 8.1 seeing the 2TB logical drive, you will lose the OS if you didn't create the array first. Sticking an existing drive into the array will cause that data on that drive to be lost.

As far as the largest logical drive 8.1 can see, I think it's the limit of GPT (9.4ZB with 512-byte sectors, or 75.2ZB with 4k sectors, that's Zettabytes. Beyond enormous.)

An M.2 SSD will have the room to be 33% faster in theory over four drives (32Gbps vs 24Gbps), and have 4 times less likelihood of a premature failure.

Someone correct me if I am wrong.

Ok so from what I read there is basically no benefit to raid 0. I was told by someone that if you use raid 0 your SSDs will read/write/boot an OS much faster than normal but that doesn't appear to be the case according to this article. Thanks.

This is correct. The only thing you 'gain' is greater fail potential.

I am going to be running four intel 730 series in raid 0 in the upcoming weeks, I just read an article where it improved the read/write speeds by 70 percent. Intel actually recommends you to run in raid 0. SSDs can actually handle the bandwith while other regular hard-drives cannot. If you have the money to do so, Run it, and give us some feedback :D I would like to know the difference between the evo pro and the intel 730 series my self. I'll run some test's and report back in a few weeks. I dont understand why people are saying the greater fail potential when the manufacturers recommend it. Their just jealous because they cant afford 4 solid states :p

You'd be wrong. My current system has 1.5TB of SSD space, across 4 drives.
No RAID in evidence.
