U.S. drive makers benefited most from the demand surge. Scotts Valley, California-based Seagate Technology extended its lead in the market, accounting for nearly a third of worldwide shipments during the three month period, iSuppli says.
The company made 30.5 percent of global hard drive shipments during the second quarter, up from 28.6 percent in the first quarter. Western Digital retained its second-place ranking in hard drives during the same period, at 17.6 percent, while Maxtor fell one spot to fourth place with a 13.5 percent share of shipments, according to iSuppli.
Japanese companies fared worse than their U.S. rivals, but Hitachi Global Storage Technologies rose a notch to third place with a 15.5 percent share of global hard drive shipments.
Toshiba remained in fifth place with a 7.7 percent share of unit shipments. The company started this week shipping 1.8-inch hard drives based on new perpendicular recording technology.
Perpendicular storage technology is a method of data storage that is only just beginning to come into commercial use in hard drives. It allows much more data to be stored on a disk because the magnetic particles on which data is stored stand perpendicular to the disk's surface, so more of them can be packed onto the disk than in the current longitudinal recording method in which they lay flat.
Fujitsu's hard drive operations placed seventh with a 6.7 percent share of hard drive unit shipments. The company does not serve the fastest growing segment of the hard drive market, the consumer electronics segment.
South Korean technology powerhouse Samsung Electronics took sixth place, with a 6.9 percent share, up from 6.6 percent during the first quarter, according to iSuppli.
