Facebook uses 10,000 Blu-ray Discs to create 1 Petabyte cold storage

  1. Facebook has developed a prototype storage system that uses a 7 feet tall cabinet filled with 10,000 Blu-ray optical discs to store one Petabyte of data. The company is planning to use this cold storage system to store rarely accessed...

    Untl one day someone kicks the prototype over...and half the discs snap and die.

    Well, when you have as much disposable income as Mark Zuckerberg does, I guess this is a fun science project. It will probably be obsolete in....oh.....the next 3 years....Maybe they can sell it on Ebay or something after that. I wonder if all the blu-ray discs are BDXL. Probably not since they said this was the most cost effective solution.

    It will be slow as hell, presumably it gets taken from the Blu-rays to a normal server if it starts getting more traffic.

    Neat idea, now why can't this be applied to hard drives in a similar matter, ie have the platters in a cartridge system and then bring them to the drive motor to be read. Transfer speed won't be negatively affect, just access time for obvious reason. Is this theoretically possible even. I can almost envision it, the containment unit will have to be seal and essentially a clean room in a box, that might be the biggest hurdle. After that it's robotics to move things around and an incredibly secure and stable mounting system for the platters. Any takers?

    Why didn't they use flash drives right off the bat?

    Isn't flash drives cheaper than Blu-ray discs and also doesn't require power to retain data and has much faster access and store speeds.

    Would this not be an issue with any solution?
    Blu-ray Disk is approximately $1 per 25GB. Can you say the same for flash drives? I don't think so, seeing as a 32GB flash drive cost around $16.

    10,000 BD = $10,000 or less

    The equivalent in flash media would be approximately 12 times if not more in cost. Who wouldn't want to save $100K, when there are options available?

    Personally this sounds like a pretty good low power consumption "backup" solution.
  10. I really hope there is more than one reading laser in there.....oh my.

    I remember how horrible the original 6 disc (data) changers were, and how Windows insisted on indexing EVERY disc upon a reboot.

    I think this was cooked up on a coke binge.

    It's easier to replace an entire HDD. Plus, it's platter/head contact which is usually the point of failure, not the actual platter shattering etc. Separate HDDs give you individual control motors + spindles + read heads etc.
