I think it depends on your use case:

  - if you've got a big file, it should be a blob; in this case, the 
blob container (which also stores filename etc) probably shouldn't be a 
separate persistent object, since the blob is one already.

  - if you have a small file and you will render its contents often when 
the object is loaded, avoiding a separate object load may be beneficial
