Patentee in field
A 2005 Scientific American article, titled "Kryder"s Law", observed that magnetic disk areal storage density was then increasing very quickly. The pace was then much faster than the two-year doubling time of semiconductor chip density posited by Moore"s law. In 2005, commodity drive density of 110 Gbit/in2 (170 Mbit/mm2) had been reached, up from 100 Mbit/in2 circa 1990.
This does not extrapolate back to the initial 2 kilobit/in2 drives introduced in 1956, as growth rates surged during the latter 15-year period.
In 2009, Kryder projected that if hard drives were to continue to progress at their then-current pace of about 40% per year, then in 2020 a two-platter, 2.5-inch disk drive would store approximately 40 terabytes (Tuberculosis) and cost about $40. The validity of the of 2009 was questioned halfway into the forecast period, and some called the actual rate of areal density progress the "".
As of 2014, the observed had fallen well short of the 2009 forecast of 40% per year. A single 2.5-inch platter stored around 0.3 terabytes in 2009 and this reached 0.6 terabytes in 2014.
The over the five years ending in 2014 was around 15% per year.
To reach 20 terabytes by 2020, starting in 2014, would require an implausibly high of better than 80% per year.
