I´m waiting for this a very long time now: Over 10 years the technology of the Hyper CD
is available, but not official for standard users. The first working prototype was shown 1999.
Capacity: 1 PB (with possibility of extension up to 100 EB) 100 Exabyte = 100.000 Petabyte = 100.000.000 Terabyte = 100.000.000.000 Gigabyte!!!
(that´s multiple times more than 64 bit processors can theoretically adress)
Medium transfer rate: 300 Mbit/s (may be more) ... today it can be surely much faster
Hard drive dimensions: 80 x 150 x 300 mm (with some optimizing it should be possible to shrink this a bit)
Disk dimensions: 1.2 mm ø 120 mm
Temperature resistance: up to 550°C (ok for my needs
Maximum usage period: 5,000 years - all over 100 years is enough in my opinion
With this you can save the complete computer & internet history up to the next 50 years without problems on one disc, but I think this is the reason why we won´t get this storage device during the next 50 years.
Meanwhile until it´s available I personally changed to HD storage this year - I´m still copying all my discs (self burned & originals) as mds files there.
