A surge could have created some damage. Do you use a UPS?
The WD Red has a 3-year warranty, so you can RMA it. Western Digital will send you a recertified replacement, not a new disk. I'd probably do the RMA, but also buy a new replacement disk for the NAS. Then either use the RMA replacement somewhere else, or keep it on hand as an emergency spare.
The btrfs file system will show some space allocated even if the volume is empty. So that part is normal.
Can you download the logs, and look at the disk_info.log? You can post it here (removing the two serial numbers if you like).
If both disks look healthy, I'd do a factory reset next (since there was file system corruption in the OS partition earlier on). But I think we should confirm disk health first.

The load cycle count on the first drive is way too high for a WDC Red - something is odd there.
I think I'd try the reset anyway, but maybe repost the stats again after the reset completes.
After doing a Factory Reset (with 2 other new disk, - trying not to lose any data from the previous marked corrupted disk meant for RMA), the newest firmware (6.6.0) was installed automatically and the stats are:
Successfully completed diagnostics System
- No errors found.
Logs
- No errors found.
The system is resyncing which will take another 3 hrs. After that I will try to replace the two disks with just the one which is meant for RMA to see if I could recover data.
Good news is that the REadyNAS is accesible again through the File Explorer.

Just make sure the NAS is powered down when you switch the disks. I'd label the new ones by slot (not strictly necessary, but does no harm).
I hope you can recover data.
Unfortunately the RMA disk is no longer readable.
It is packed to be shipped.
Thanks for all the great help and information. It was a pleasure.
