Facebook stores billions of photos in their data centers. However many of the photos that are stored on the servers are rarely looked at anymore because they were uploaded years ago. This is why the company is transferring many of these old photos to “cold storage” facilities in their data centers located in Prineville, Oregon. The servers will be there on a standby basis, which makes them perfect usage for old photos. Facebook will consume less energy at their data storage locations this way also. The photos may take milliseconds longer to open than the newer photos, but I’m sure people will hardly notice the difference.
