I'm surprised by the numbers here as well. I have a late 2016 MBP 512GB (used daily) and the numbers are nowhere similar. It's a bit worrying though that I'm the only one in this thread with error log entries.

Is there a way to look up that error log?

To be honest I'm not sure how to interpret it. There are some tools on Linux to read this information but the output doesn't really seem more useful.

I did a quick search earlier and it seems these are informational only and not necessarily persistent warnings. Some discussion suggested that some unsupported requests to the disk can result in these, but I don't know for sure.
