HDD densities to double by 2016: IHS

SAN FRANCISCO, USA: According to market research firm, IHS iSuppli, maximum areal densities in hard disk drives (HDD) are expected to more than double during the five-year period from 2011 to 2016, spurring continued growth for HDDs in storage-intensive applications such as video and audio systems.

As per IHS, HDD areal densities are estimated to reach 780 Gb per square inch per platter, this year. It will then rise to 900 Gb per square inch next year. As per IHS's predictions, the five-year compound annual growth rate (CAGR) for HDD areal densities from 2011 to 2016 will be equivalent to 19 per cent. HDD areal densities measuring data-storage capacities are projected to climb to a maximum 1,800 gigabits (Gb) per square inch per platter by 2016, up from 744 Gb per square inch in 2011, says IHS.

"The rise in areal density will pave the way for continued growth of the HDD industry. Densities will double during the next five years, despite technical difficulties associated with the perpendicular magnetic recording technology now used to create higher-areal-density hard disks. In particular, growth opportunities will lie in applications associated with mass enterprise storage requirements, gaming, and in digital video recorders where massive capacity is required to store high-definition video,'' said Fang Zhang, analyst for storage systems at IHS.
