So, I did a whole lot more research, and it seems that Intel won't make it easy to use. It's all command prompt, and the drivers barely support Win7....
I didn't find anything that said that Windows sees it as multiple drives, nor that it used software RAID, but I did see that the download tools (the software) is what you would use when inspecting and configuring a RAID of these drives.
Does that mean it is a software to manage a hardware RAID or a software to manage configure a software RAID? I don't know.
I was looking at Intel's website and reading the details of the downloads (software drive management tools, drivers, firmware updates).
To get Win7 support, you have to go back to older versions of the drivers, and even then, you don't get complete support for Win7.
DC P3600 is discontinued, as far as Intel is concerned, even though you still find them for sale, everywhere.
I started looking at the 4TB DC P4500. It also has limited Win7 support.
The "enthusiast" line of product absolutely only supports Win10, so it's a no go....
In then end, I guess I will not get the Intel Fultondale 3 DC P3600 AIC 2TB PCI-Express 3.0..., nor the DC P4500 model, either.
I guess I'll start looking at M.2 drives. I just hope they've gone up in capacity. Believe it or not, 500GB is not enough space for me. LOL That's how big they seem to make them.
LOOK WHAT I FOUND!!
2TB! Now all I have to find out is if it's compatible with Win7 and my mobo....
So, my mobo is compatible, and so is Windows 7!!
