Using an innovative nanotechnology, IBM scientists in Switzerland demonstrate a data storage density of a trillion bits per square inch -- 20 times higher than the densest magnetic storage available. IBM achieves this density -- enough to store 25 million printed textbook pages on a surface the size of a postage stamp -- in a research project called "Millipede."

IBM records 1 terabyte (TB) of data to a linear digital tape cartridge, storing 10 times more data than any linear tape cartridge then available. (One terabyte is equal to 16 days of continuously running DVD movies or 8,000 times more data than a human brain retains in a lifetime.) The 1 TB initiative had been under development since April 2001 at IBM's Almaden Research Center in San Jose, Calif., and IBM storage product development laboratories in San Jose, Calif.; Tucson, Ariz., and Yamato, Japan. (This achievement coincides with IBM's 50th anniversary of magnetic tape storage that ushered in a new era of information processing. In May 1952, IBM introduced the Model 726 tape drive which stored a total of 1.4 megabytes -- equal to one floppy disk in 2002 -- on a movie reel over 12 inches in diameter and using a special tape media developed by 3M.)

IBM debuts the Travelstar GNX hard disk drive in February.

In May, IBM supports the introduction of "Bluefin," a new technology that is expected to provide an industry-wide management solution for interoperable storage area networks.

The following month, the company ships its 10,000th IBM TotalStorage Enterprise Storage Server ("Shark"), to Commerzbank, a leading international investment and banking institution based in Frankfurt, Germany.

In July, the company introduces: the IBM TotalStorage Enterprise Tape Drive 3590 Model H, that stores up to 50 percent more information than the previous model; the Ultrastar 146Z10, an industrial-strength server hard disk drive for use in the most intensive business environments (it is the first 10,000 rpm hard drive of its generation to ship in volume, with a top capacity of 146 gigabytes); the IBM TotalStorage Enterprise Storage Server ("Shark") Model 800 powered by IBM's copper microchips and industry's first 2-Gigabit-per-second Fibre/FICON data transfer rates; and the IBM TotalStorage Network Attached Storage 100, a thin self-managing, self-healing appliance for e-mail archiving, server consolidation, storage backup or archiving paper documents.

In September, the company debuts the IBM Deskstar 180GXP, the world's fastest desktop hard disk drive.

In November, IBM launches the Travelstar 80GN, the world's highest capacity mobile hard disk drive of 80GB, made possible by enhancements to the company's patented "Pixie Dust" technology which boost storage density by 100 percent. In addition, IBM announces the IBM TotalStorage Network Attached Storage 200, TotalStorage NAS Gateway 300, and TotalStorage FAStT, new network attached storage systems that double the processor speed and storage capacity of previous models.
