This may be known already, but I noticed the following message in syslog
during boot:
Btrfs detected SSD devices, enabling SSD mode
Btrfs is right in a sense: there is a SSD involved, but there's a HDD as
well. I don't think it is an issue, but I have no idea how "btrfs' SSD
optimizations" will interact with bcache. Might be interesting.
