Revision as of 07:42, 18 January 2018
Mark Kryder (born October 7, 1943 in Portland, Oregon) was Seagate Corp.'s senior vice president of research and chief technology officer.[1]
Kryder holds a Bachelor of Science degree in Electrical Engineering from Stanford University and a Ph.D. in Electrical Engineering and Physics from the California Institute of Technology.[1]
Kryder's law projection
A 2005 Scientific American article, titled "Kryder's Law", observed that magnetic disk areal storage density was then increasing very quickly.[2] The pace was then much faster than the two-year doubling time of semiconductor chip density posited by Moore's law.
Inside of a decade and a half, hard disks had increased their capacity 1,000-fold, a rate that Intel founder Gordon Moore himself has called "flabbergasting."
In 2005, commodity drive density of 110 Gbit/in2 (170 Mbit/mm2) had been reached, up from 100 Mbit/in2 (155 Kbit/mm2) circa 1990.[2] This does not extrapolate back to the initial 2 kilobit/in2 (3.1 bit/mm2) drives introduced in 1956, as growth rates surged during the latter 15-year period.[2][3]
In 2009, Kryder[4] 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 (TB) and cost about $40.
Kryder rate
The validity of the Kryder's law projection of 2009 was questioned halfway into the forecast period, and some called the actual rate of areal density progress the "Kryder rate". As of 2014, the observed Kryder rate 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 Kryder rate 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 Kryder rate of better than 80% per year.[5]
Awards and honors
Mark H. Kryder is an elected member of the National Academy of Engineering, a Fellow of the American Physical Society and a Fellow of the Institute of Electrical and Electronic Engineers (IEEE).[1] He was Distinguished Lecturer for the IEEE Magnetics Society, and has been awarded the IEEE Magnetics Society Achievement Award and IEEE Reynold B. Johnson Information Storage Systems Award.[6] Kryder received the Pingat Bakti Masyarakat[7] from Singapore in their 2007 National Day Awards.

Currently 2.5-inch drives are at 500GB/platter with some at 600GB or even 667GB/platter – a long way from 20TB/platter. To reach 20TB by 2020, the 500GB/platter drives will have to increase areal density 44 times in six years. It isn't going to happen. ... Rosenthal writes: "The technical difficulties of migrating from PMR to HAMR, meant that already in 2010 the Kryder rate had slowed significantly and was not expected to return to its trend in the near future. The floods reinforced this."
