Old enough to know better: A dumb question, but what is the actual difference between the disk in TFA, and todays 1TB platters? More refined metals? stronger magnetic particles?
Any Pie Left: In two years, the Square Kilometer Array project will start up, and this network of radio telescopes will generate an exabyte of new data, each day. The Human Brain Project in Europe, will probably generate that much every two days.IBM is heading a consortium of computer and internet providers to create an architecture that can handle that firehose of incoming data, store it, and process it. I have no farking idea HOW they are going to do it. But we're all going to be the beneficiaries of that increased data capacity, with higher-speed networks to link it, when they commercialize it.In just 2-4 years from now, we'll see an improvement that makes today's tech look like this archival video we've just watched.
Nicholas D. Wolfwood: Old enough to know better: A dumb question, but what is the actual difference between the disk in TFA, and todays 1TB platters? More refined metals? stronger magnetic particles?No one single difference, but the accumulated effect of *many* improvements:Plated media instead of oxide coating (more bits per inch)Vertical domain recording (if a bit is like a domino, stand it on end instead of laying it flat)More efficient encoding (more bits stored in fewer flux changes)Zone-based recording (more sectors per track on the longer tracks on the outer parts of the platter)Fantastic recording heads with the hard drive equivalent of ultra hi-def (like switching from a paint roller to a fine point marker to write a track)... and many, many more.

nekom: Old enough to know better: A dumb question, but what is the actual difference between the disk in TFA, and todays 1TB platters? More refined metals? stronger magnetic particles?That isn't a dumb question at all, I'd like to know the answer myself. My guess would be better read/write heads allowing for much higher density of data. But I've never worked in hardware so I'm quite likely wrong on that.
