As you have noticed, the rebuilding process takes an increasingly long time (I think it was about 36h when I last used 4TB drives on an Areca RAID card). Longer term, I would strongly suggest leaving RAID behind. Hardware RAID means you'll have to switch ports or change RAID to JBOD setting on the card's bios. I'm not sure if you're running software or hardware raid, but the safest is probably to power it down, and do a surface scan each of the drives separately (read only!) using a bootable tool. You may want to do that scan on each of the drives to see if they're still healthy. If the rebuilding process kicks in, something has changed on one (or maybe even both) of the drives (which could indicate deteriorating health). I assume the RAID drives didn't see any changes during that process, but you should even be able to disconnect a drive in the array when offline, and for example do a non volatile surface scan.

To my dismay, the RAID resynchronisation process started.

I conclude the mere fact of seeing both drives disconnected is recorded on the Windows boot volume on the NVMe drive, and enough to trigger a resync. A small dialogue box will appear, showing you the process to stop the progress.
#Stop softraid update update
Alternatively, you can click on the 'Stop' link available under the Windows Update option on the top left side of the window. The RAID resynchronisation process has started. Here you need to right-click 'Windows Update', and from the context menu, select 'Stop'.
#Stop softraid update upgrade
Reboot, logon, check volumes are in sync, orderly power off. After you upgrade your servers to Oracle VM Server Release 3.4.5, PVM guests are not disabled by default, because that.a power loss requires like 5 hours of uninterrupted on time. The RAID volume resynchronisation process after e.g.
#Stop softraid update windows 10
I have a working 3TB software RAID volume under Windows 10 on my primary work machine, physically two 3TB rotating rust disk.
