The Magnetic Hard Disk Drive: Today's Technical Status and Its Future

Edward Grochowski, Computer Memory Storage Consultant, and Peter Goglia, Plasma Therm




The ubiquitous magnetic hard disk drive continues to occupy a principal role in all storage applications, shipping more bytes than all other competing product technologies. The emergence of cloud computing has firmly established the future of HDD products well into the next decade. The emergence of IOT will continue the demand for HDD bytes. This presentation will discuss today's HDD, its technical characteristics and storage capacity as well as cost per gigabyte. The technologies which enable these properties such as; form factor, interface, shingle write, helium ambient and yet to be implemented TDMR and heat assisted magnetic recording (HAMR) will be detailed. A projection of disk drives of the future will be made and their competiveness to flash as well as emerging non volatile memories (NVM) will be discussed.






Ed Grochowski, Computer Memory/Storage Consultant: Dr. Ed Grochowski is a well known speaker on storage technology. He has a long career association with the computer industry, a majority of which were with IBM. Ed worked at the IBM Almaden Research Center where his interests included hard disk drive evolutionary trends. He extended these interests to memory and storage technologies as SSD and NVM devices. Ed's charts are frequently used to describe storage technology progress by numerous industry presenters at many conferences. He holds twelve patents and has authored and presented numerous articles on HDD, Flash memory and NVM technologies. Ed holds a PhD. from New York University. He was a long time coordinator of the HDD 4K-byte sector standards committee, and is a member of the IEEE. For more information see

Peter Goglia is Vice President of Ion Beam Operations at Plasma-Therm NES and President of VeriTekk Solutions. He has 34 years of experience in the disk drive industry. Peter was CEO of Nano-Etch Systems and has held key R&D rolls as CTO for Xyratex Storage Infrastucture Division where he was responsible for technology development and growth strategies for HDD capital equipment. He also held senior positions at WD, Seagate, Control Data and Hewlett Packard. At WD he was VP of R&D in the Magnetic Head Operation including device development, slider, HGA design and process development. At Seagate, he contributed to the recording head development in both design and process. At the Disk Memory Division of Hewlett-Packard he was a senior member of the technical staff. He holds 6 patents and has been an invited speaker at industry technical and trade events. Peter has a Ph.D. in Mechanical Engineering, from the University of Illinois.
