What in addition is the database doing for you?


1. arranging transaction rollback -- get rid of a blob not completely
stored.

2. giving you ability to search by multiple tags associated with the
blob.

3. making sure backup includes everything current.

4. if the input data exist in the filesystem, rather than coming in
the wire, you will have an extra disk copy.

5. deal with concurrency problems.

My gut feeling is let the database handle it , and only if you
discover performance problems, experiment with using manual files.
 

If you don't actually serve the files, then having them separate would
make more sense.  You are then just maintaining an index.
