    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).

    Software Raid 1. Can not Add Mirror !

    Hi there

    I believe to use mirror / striping in RAID 1 configuration on Windows you need to use Storage spaces - so set the 2 HDD's into a storage space and then you can adjust striping / mirroring.
