Out with the old and in with the new. That’s the theme of a recent report from IHS iSuppli that predicts HDD revenue will drop roughly 12% this year due to a “relentless onslaught” from SSDs and mobile devices. IHS iSuppli expects HDD evenue to drop to about $32.7 billion this year (down 11.8% from 2012) and remain flat through 2014 reaching $32 billion. IHS Analyst Fang  hang says that among the myriad challenges the HDD industry faces are falling SSD prices. HDDs, however, will remain the dominant storage form factor this year, “especially as demand for Ultrabooks picks up and hard drives remain essential in business computing.” The longterm forecast for PC optical drives isn’t much better, with IHS painting a “grim” scenario due to continued challenges from the likes of thinner PC designs. “Optical drives could eventually be abandoned by PC makers altogether,” the report warns.
