From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Could you show us the raid type and info with
btrfs fi us /home
, and then the errors encountered on each disk withbtrfs dev sta /home
?Few possibilities here:
Could be something wrong with the SSD - is it a Samsung one by any chance? There was a firmware issue that caused the SSD lifespan to degrade at a higher rate than normal... This article only covers the 980 but I believe there were a few models affected

It also could be that whatever files were corrupted have been deleted (maybe browser cache files etc.) or the allocated block is corrupted but contains no files within it. After running a scrub, the names of files within a corrupted block are shown in dmesg - if there's none then I think you're fine, but strongly consider replacing the SSD/updating its firmware/checking its SMART diagnostic data to see if its ok.
The error counter can be reset with
btrfs dev sta --reset
to see if these errors pop up again after trying a resolution
