Windows 10: Can I use a RAID 1 drive array as my Windows boot drive?

I have an old desktop pc (Dell Inspiron 620) that I want to use as a home file server. This PC will only hold two hard drives. I would like to install two identical 4TB drives and have Windows treat them as a RAID 1 array. Is this possible? If so, are there instructions for using a RAID 1 array as the Windows system drive. Thanks.

Trouble creating a RAID 1 Array

Originally, I wanted to create a RAID 1 Array using USB Drives lying around and test it out and see how well RAID 1 works. A message popped up when I clicked on the partition I wanted to mirror and said the operation failed because the Disk Management
Console is not up to date. It suggested I refresh it, relaunch it, or even restart my computer. I tried all three things, and it still wouldn't let me mirror the partition. Then I realized that maybe Windows won't let me create a RAID 1 Array on USB Drives,
so I went to the original plan I was going to do and grabbed my 500GB External HDD and my 120GB External SSD (they are both USB 3.0 connected enclosures) and when I tried to mirror a partition on my 500GB HDD using my SSD, it wouldn't let me use the SSD to
mirror it. So then I tried using my internal windows 10 SSD to mirror my HDD. But, I needed to shrink my main partition on my internal SSD and it wouldn't let me shrink it saying there was a certain amount I could shrink it to, but I could only shrink 135MB
at max and I have 89.4GB free on that partition. Any suggestions and help would be appreciated (and by the way, if you're wondering why I'm trying to run RAID 1 on an external HDD/SSD is just for testing and more file redundancy and performance).

 

raid 0 array installation

im trying to install windows 10 on a raid 0 array and when i select the drive to install to it splits the array and then cannot install to either parts

Me

the array is 3 1TB drives. it sees it as 3 TB in the installation manager, but when i try to select it it splits it to a 2TB drive and a 1TB drive. it then wont let me install to either drive

I have windows 10 pro

I set up the array in bios and all is well

I boot to installation media dvd and it says "a media driver your computer needs is missing.

I select the new raid driver and install it.

Then it asks for installation destination, it sees my 3 TB array but when i click on it it separates it into a 2 TB drive and a 1TB drive and then it gives me an error saying " we couldnt install windows in the location you chose. please check your media
drive. heres ore info about what happened: 0x80300024"
