Are disk years like dog years?



iGizmo’s retrospective on the disk drive’s brief but frenetic history is worth a look.  The disk drive industry has done more in its fifty years than most industries accomplish in multiple centuries. 

Check out the change in cost per megabyte in just the past 30 years:

– 1980: $233
– 1985: $71
– 1990: $9
– 1995: $0.75
– 2000: $0.0118
– 2005: $0.0006

Imagine what the next five decades will bring.  Realistically, I don’t think we have the faintest idea.

But take your best shot – visions and comments welcome.
