Question Replace failed drive i RAID 1 set

Hello,
I have an (old) Asus Prime Z270-A MB that among other features is equipped with Intel Rapid Storage Technology in UEFI BIOS.
When I set up the computer it was not possible to create a RAID set in Windows 10 so I used the Intel option to create it in the BIOS thus presenting the RAID set as one drive to Windows.
This has been working flawlessly for some years now. However one of the SSD:s in the RAID set is getting degraded so I want to replace it. I can't see any options for doing this in the Intel part of the BIOS and wonder how to proceed.
Is it possible to just shutdown the computer, disconnect the failing SSD, replace it with a new and then start the computer. Will the RAID set start rebuilding by itself or must I do something to initiate it? Would appreciate some advise. I don't want to risk loosing my data.
Running Windows 10 with all patches also latest version of Asus BIOS for my MB.
THX/Hans

If you have it set up as a RAID 1 then all you have to do is pull out the drive that is dying and replace it. The RAID array should begin a rebuild immediately upon restart. That is how it works on enterprise RAID arrays and even consumer NAS's that use RAID.

Thanks for a quick answer.
Ok, I understand it works on enterprise RAID arrays and consumer NAS (did that once myself) but will it work on the RAID utility that is on my MB? That question is what makes me a bit nervous.

First off, do you have a known good backup of ALL data on this RAID array?
If not, do that now. Before you do any messing around with the drives.

I agree with USAFRet in taking a full backup first. That way your data is safe should something go wrong.

After doing that the utility on the MB should rebuild the RAID 1 once a new drive is put in. At worst you will have to add the new drive to the current array in BIOS and at which point the array will start to rebuild.
