If I can store a hard drive on a disc as backup - My life is complete.

Toodles.

You won't be able to store a modern, large~ish drive on blu-ray anytime soon. The consumer can't anyhow.

By the time the consumer can, the new hard drives of that time, will be too big XD

But yeah, pretty cool. But I can't see it being used much, except perhas by people who wan't to back up large amounts of data, or are involved in graphics/video or something, production.

Wouldn't an external hard drive be easier and cheaper? £54 for 500gb external drive atm.

If only I can burn the Blu-ray discs as fast as maximum CD's writing speed, my whole life will then be fulfilled!!!!
