In need of advise about saving large binary data

Hello,

i am working on a project where users are able to submit any ammount
of large binary files.
Currently all data is stored in a MySql database, but i am uncertain
if it would be better/more efficient/faster to store the binary files
on the filesystem. This would certainly save MySql from a lot of work,
but ensuring data integrity could become complicated.
I am uncertain if it is a good idea to move the binary data out of the
database, so i appreciate any information.
Thanks in advance.
