Facebook has long been known to be the largest photo repository in the world. Today on the Facebook Engineering blog it was reported that Facebook today hit the milestone of 10 billion photos across the entire site. The 10 billion photos each have multiple copies stored, totaling 40 billion files in whole.
According to Jeremiah Owyang back in January, Facebook photos draw more than twice the traffic of the next 3 competing sites combined. In November of last year, TechCrunch reported that Flickr hit their 2 billionth photo.
Some further stats from the article:
- 2-3 Terabytes of photos are being uploaded to the site every day
- We have just over one petabyte of photo storage
- We serve over 15 billion photo images per day
- Photo traffic now peaks at over 300,000 images served per second
