The Tech Report writes 1.8-inch HDDs, which are used in small devices like iPods, are expected to reach a capacity of 1TB by 2014. This information comes straight from Seagate, world's biggest HDD maker. The company's biggest 1.8" HDD today has a capacity of only 12GB.
After telling the editor that pocket-sized hard drives had already reached 120GB and that their capacity was increasing at the rate of 40% per year, one of the reps said in an e-mail, "[a Seagate slide] shows a 2.5-inch drive (the ones used in laptops) reaching 1TB by 2013. Using that calculation and assuming 40% growth stays as the annual growth rate, a 1.8-inch (the ones used in PMPs like video iPods) would reach 1TB by 2014." The reps also revealed that Seagate is talking about the possibility of making 1" hard drives with 100GB capacities by 2011 or 2013.
