Maybe if you grouped multiple operations on bigger transactions, the I/O
savings could be enough to buy you the ability to vacuum once in a
while. Or consider buffering somehow -- save the data elsewhere, and
have some sort of daemon to put it into the database. This would allow
to cope with the I/O increase during vacuum.
