Mark Kryder (b. 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[edit]

Growth rate of HDD storage space compared to Moore's Law using Apple consumer products (1984-2001).
Hard drive capacity over time following Kryder's Law (1980-2011).

A 2005 Scientific American article, titled "Kryder's Law", describes the work of Mark Kryder and the fact that magnetic disk areal storage density is increasing very quickly, at a pace much faster than the doubling in semiconductor chip performance occurring every 18 months in Moore's Law.[2]

"The density of hard drives increases by a factor of 1,000 every 10.5 years (doubling every 13 months)."

In 2005, commodity drive density of 110 gigabit/in2 or 170 megabit/mm2 had been reached. This does not extrapolate all the way back to the initial 2 kilobit/in2 drives introduced in 1956, as growth rates increased with the advent of institutionalized strategic technology re-investment such as the MTC (Magnetics Technology Center later the Data Storage Systems Center).[2][3]

A article reports on a 2009 study by Mark Kryder.[4] According to the report, if hard drives continue to progress at their current pace, then in 2020 a two-platter, 2.5-inch disk drive will be capable of storing more than 14 terabytes (TB) and will cost about $40. It also investigates 13 up-and-coming non-volatile memory technologies to see whether one of them might outperform hard drives on a cost-per-TB basis in 2020.

Awards and honors[edit]

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.[5] Kryder received the Pingat Bakti Masyarakat[6] from Singapore in their 2007 National Day Awards.
