I tried backing up a few files (<1GB) to my NAS but each time I got an read/write error. The issue is only occurring on my Raid1 array and I'm having no issues copying the same data to another drive on my NAS -- leading me to believe one or both of my RAID1 drives are failing although I haven't gotten any reports from a failed smart test (and I am running them regularly).
Here's the SMART output for the first drive in the array (it's a WD Green that I ran without WDIDLE for years, and thus the load cycle count is dangerously high): (Yes, I know I should be replacing the drive/s even if they aren't failing right now).
Drive #2:
