/dev/sdb is dropping a lot of reads and writes. Is /dev/sdb in a
SATA-USB enclosure of some kind?

Curious but I don't think it's related.

Something is definitely confused but I'm not sure what or why.
$ sudo btrfs insp dump-s /dev/sdb1 | grep dev_item.total_bytes
Compare that value with (Sectors * 512) from:
$ sudo fdisk -l /dev/sdb
The fdisk number of bytes should be the same as or more than the btrfs bytes.
$ sudo smartctl -x /dev/sdb
That might require installing the smartmontools package.
