OK it is no rocket ship compared to a SSD but would like to be able to get more out of removable storage with Calibre - (but probably would require the database to be on the SSD only needing to point to files which dont change on the SDHC - which as I understand is not how Calibre works?)
It may be coincidence but changing in device manager - disk drives - multiple card reader USB device - properties - policies - select better performance (enables write caching) changed the 'move on to the next book in edit metadata' time from 60s+ to a consistent 25s.
