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]

A 2005 Scientific American article, titled "Kryder's Law", describes the work of Mark Kryder and the fact that magnetic disk areal storage density was then increasing very quickly.[2] The pace was then much faster than the doubling in semiconductor chip density occurring every two years in 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."

Kryder's Law[2]
Growth rate of HDD storage space compared to Moore's Law using Apple consumer products (1984-2001).

In 2005, commodity drive density of 110 Gbit/in2 (170 Mbit/mm2) had been reached up from 100 Mbit/in2 circa 1990.[2] This does not extrapolate all the way back to the initial 2 kilobit/in2 drives introduced in 1956, as growth rates increased with among other things 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 by Mark Kryder[4] projected that 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. The article 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.
