Large-Scale Video Archiving?

BondHeadGuy asks: "Ok, say you have 1000+ cameras emitting 30 frames/second worth of 640x480 grayscale video...and you have to store it indefinitely. What do you do? This is a real question, believe it or not. 30 frames/s * 300 KB/frame = 9 MB/s per camera. 100:1 video compression brings that down to ~90 KB/s. But 90 KB/s * 1000 cameras = 90 MB/s, or ~8 terabytes/day. Retrieval, though, can be essentially arbitrarily slow. Reliability should be good enough to not be annoying long term. Is there a solution that: has 8 TB/day storage capacity, can handle the 90 MB/s write speed, and lets you save some bucks on the (slow) read side?"

    Do you work for that new "Homeland Security" agency??

    Pros: Extremely high write speed
    Cons: Hard to get data back out, but since "Retrieval... can be essentially arbitrarily slow" you've can just re-film whatever it was that you missed. With the money you save on the video gear, you should have a nice little production budget, too...
