Facebook Puts 10,000 Blu-ray Discs In Low-Power Storage System 153
itwbennett writes "Facebook said last year that it was exploring Blu-ray for its data-center storage needs, and on Tuesday it showed a prototype system at the Open Compute Project summit meeting in San Jose, California. It designed the system to store data that hardly ever needs to be accessed, or for so-called 'cold storage' (think duplicates of users' photos and videos that it keeps for backup). The Blu-ray system reduces costs by 50% and energy use by 80% compared with its current cold-storage system, which uses hard disk drives, said Jay Parikh, Facebook's vice president of infrastructure engineering."
It's a prototype, and they're also evaluating low power flash as another alternative to keeping seldom accessed data on hard drives.

So that will be several million inactive profiles. I hope they've made their solution scalable, pretty soon they'll be storing 75% of their current profiles on those discs.

When you delete your account, somebody will go and get the corresponding disk, copy it (except your data), and destroy the old disk.
It's write-once only if you don't consider "destroy" a write-operation.

For that first year, he was probably trying fucking a bit harder rather than worrying about data recovery. Priorities, lonely internet dude, priorities.
