Apparently Linux has a facility for 'optimal IO size' of block devices (see 'lsblk -o NAME,OPT-IO') but on my system I only have a value for Linux md RAID devices (which happen to be RAID0, and the OPT-IO value is the stride). All of the other devices have OPT-IO 0.
Perhaps more work needs to be done to bubble some value up from the hardware.
