You're trying to reinvent load-balancing and a CDN (Content Delivery 

Bandwidth is cheap. Scattering your media across some cobbled-together 
distributed system isn't going to make any difference in bandwidth 
consumption. When you say "it consumes too much bandwidth", what is the 
real problem? Your server can't keep up? You're trying to serve up these 
files using some DSL or cable modem connection? Your MySQL can't keep 
up? That's not an unusual situation, by the way. By default, MySQL uses 
MyISAM table types. That'll be a big bottleneck on systems that need to 
have write access to tables because MyISAM only supports table locks. 
You haven't provided enough details.
