Does anyone know whether fragmentation could be a performance issue for the Kobo filesystems?

The device's internal filesystem is EXT format which is supposed to be highly resistant, if not completely immune, to fragmentation effects.

But the user filesystem where the main database, book and image files are stored is FAT format which can suffer badly from fragmentation problems, especially as it starts to fill up.

If the FAT filesystem does suffer from fragmentation then perhaps having a larger μSD card that always stays at least half empty might help.
