Hard-drive makers are revving their mobile products and shifting into high gear.
IBM and Toshiba separately announced this month that they're boosting the rotational speed of upcoming mobile drives from 4,200RPM to 5,400RPM. The faster rotational speeds are expected to significantly improve performance; IBM expects performance to increase about 25 percent.
While difficult to develop, performance improvements continue in the hard-drive industry, as customers constantly demand faster, smaller-sized drives that boast larger capacities. Innovations for mobile hard drives are especially difficult, though, because of the added issues of battery life, heat and noise, according to IDC analyst David Reinsel.
