By the time we have blu-ray up in the 100GB range, it's going to be too
small for much of the use you're thinking of because we'll be into the
multi-terrabyte drive arrays even for modestly sized businesses. I've
heard about a new format that's probably about 4-5 years out from the
first consumer products that will store 1TB on a single layer. However
even that may be too little too late if drive arrays become commonplace.
As for off-site backups, dropping an array in a few remote data centers
would do the trick, no? Or do the insurance policies specifically state
backups must be made on some form of removable media - therefore making
them highly suspectible to theft, loss, degradation and corruption?

Technical details. Both formats provide the same end-result. I'm talking
about differences that you don't need to be an engineer to understand.
VHS and Betamax had differences that the consumer could understand and
evaluate. With HD-DVD and Blu-Ray, there are virtually no differences in
either the video or data market segments.

It's not broken. It's...advanced.
