Where Facebook Stores 900 Million New Photos Per Day

1sockchuck writes: Facebook faces unique storage challenges. Its users upload 900 million new images daily, most of which are only viewed for a couple of days. The social network has built specialized cold storage facilities to manage these rarely-accessed photos. Data Center Frontier goes inside this facility, providing a closer look at Facebook's newest strategy: Using thousands of Blu-Ray disks to store images, complete with a robotic retrieval system (see video demo). Others are interested as well. Sony recently acquired a Blu-Ray storage startup founded by Open Compute chairman Frank Frankovsky, which hopes to drive enterprise adoption of optical data storage.

They could save space

They could just delete most of the photos after they age a bit, analyzing it with some of their AI whiz-bang software.

If anyone ever asks to see the image again, they can just show one that is "close enough" and nobody would ever know the difference.

I personally, have never posted a photo to Facebook, so I'd be OK with that.

After 3 months of no views, just replace them with a goatse image.

Dear God, there is more than one!?!
