a 500GB HDD isn't much going by desktop equipment, if you happen to use SCSI drives, well yeah you have a very valid point.

We're obviously talking different scales, I'm talking business applications, not home. I'm considering Petabytes of data not Terrabytes (hence the reason I stated a replacement for TBU as a backup medium).

At least drives in the future may have a healthier MTBF being solid state.

When I look at my home systems, I've got ~8TB all up but files that aren't replaceable or retrievable elsewhere would fit on a single CD very easily.

Are you sure, I remember CD's had a storagle life of 10 years (before you get major errors in data transfer). Or is this stored in a certain way (dark, cool area where it must be kept dry)?

DVD's are suggested to have a storage life of 100 years. We have to wait 90 odd years to see if that claim is actually true though. Re-writables anywhere from 25 years to 100 years. Go to the 24k gold plated DVD's and we're talking upwards of 300 years. However, if you skimp and go the cheapie blank DVD route, well... you get what you pay for.

No special storage is required but obviously you wouldn't use one as a beer coaster and expect your great grandkids to be able to see candid shots of their great grandma afterwards.

Ahh ok, so the plastic used is better. Thanks

although not compatible with any current players etc, a company called Optware has developed a disc format called HVD (Holographic Versatile Disc) which can theoretically hold 3.9TB of data, so the technology is certainly here right now for very large disc storage. But like a few have said already, for the near future at least, this sort of thing would only be practical for archive storage by industries rather than for home use.
