Why Facebook thinks Blu-ray discs are perfect for the data center
Cheap storage with a 50-year life span? Facebook spreads the gospel of Blu-ray.

Facebook has developed a prototype storage system that uses 10,000 Blu-ray discs to hold a petabyte of data.

The discs are housed in a fancy rack that holds 24 magazines, with each magazine holding 36 cartridges, and each cartridge holding 12 Blu-ray discs, for a total of 10,368. A robot lives and works inside the rack.
