Facebook Gets Three Times More Efficient At Finding Photos In Its Humungous Haystack

With more than 15 billion photos (and 60 billion image files with replication for different sizes), Facebook eats up a lot of storage with its photo application alone. Members are adding 220 million new photos every week. Facebook currently has more than 1.5 petabytes of storage for its photos, and that is growing at a rate of 25 terabytes a week. Last year, Facebook spent an estimated $30 million on NetApp storage appliances alone just to keep up with the growth of photos and other uploaded content. To reduce some of these costs, Facebook decided to engineer its own storage architecture called Haystack.
