I sure miss the CDFreaks days when we use to have CD/DVD news like this on the home page; even this story didn't seem to qualify now, with the latest being yet another about Anonymous. :sad:
Either way, it's about time someone finally created a much more robust disc, although I think at this stage it's too late.
For most consumers, storing important data on two or three HDDs is sufficient, with one HDD stored off site (e.g. car or relative's house), as the chance of two HDDs failing around the same time is highly unlikely. This optical media would be more suited for guaranteed permanent storage of data, such as museums, etc. as a few pointed out.
One other technology I would like to see is a consumer HDD that operates like a WORM media, i.e. where data can be added to the drive, but existing data cannot be overwritten or deleted. For example, a HDD in perfect working order is vulnerable to being infected or having its data destroyed or tampered with, such as if the user gets an infection that takes its data "hostage" by encrypting it and demanding a ransom to decrypt it.
