Intel Raid 1 array disconnect

[joshuajk]

In my computer I have a ssd as the boot drive and two 2tb hdd running in what should be an Intel raid 1 array. I say should because in the device manager under disk drive says "Intel Raid 0 Volume SCSI Disk Device". However in disk management the total capacity of those two drives is 1863.01 gb, indicating in my mind that it's a Raid 1 array. 

On to my real question, can I remove one of the 2tb drives and have the other drive continue unchanged? I'd like to use one of the drives for external back up rather than have a raid array.

Don't use mobo raid 1, use a backup, and if you need raid, use storage spaces in windows, or a hardware raid card.

 

If you remove a disk, It will work, but id set it up as a single disk.

Ok thanks for the advice.

So you think it is raid 1 even though device manager says raid 0?

To clarify, removing one disk will leave the data in the remaining disk unaffected?
