Hitachi Introduces New 15,000 RPM Enterprise Hard Drive.Business Editors/High-Tech Writers SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif.--(BUSINESS WIRE)--Jan. 6, 2003 Hitachi Global Storage Technologies Hitachi Global Storage Technologies is a wholly owned subsidiary of Hitachi, Ltd. Summary Hitachi purchased IBM's hard disk drive division, integrated their own HDD operations, and launched the company in 2003. today introduced its third-generation, high-end enterprise hard disk drive -- the 15,000 RPM Hitachi Ultrastar 15K73. Hitachi's newest product is a high-performance, high-reliability server-class hard disk drive, designed to excel in today's demanding data-processing environments. The 3.5-inch drive comes in a top capacity of 73 GB in an industry standard 1-inch hard disk drive "z" height. Hitachi is able to achieve an areal density The number of bits per square inch of storage surface. It typically refers to disk drives, where the number of bits per inch (bpi) times the number of tracks per inch (tpi) yields the areal density. of 31 billion bits per square inch on the new Ultrastar through a combination of antiferromagnetically coupled (AFC (1) (Application Foundation Classes) A class library from Microsoft that provides an application framework and graphics, graphical user interface (GUI) and multimedia routines for Java programmers. ) media and fluid dynamic bearing motors (FDB FDB Fluid Dynamic Bearing (hard disk technology) FDB Font Definition Block (Macromedia Flash SWF file) FDB Forwarding Database FDB First Data Bank FDB Flexor Digitorum Brevis ). The 15K73 is the industry's first 15K RPM hard drive to implement AFC media. AFC enables high areal densities by improving thermal stability which maintains data integrity. FDB also contributes to increased capacity by enabling high track density through a more precise positioning of the head. The new Ultrastar provides customers with an elite enterprise storage solution that meets today's performance needs, yet is able to maintain a low power consumption level of 12 watts (SCSI SCSI in full Small Computer System Interface Once common standard for connecting peripheral devices (disks, modems, printers, etc.) to small and medium-sized computers. SCSI has given way to faster standards, such as Firewire and USB. ) -- well within today's standards. The Ultrastar 15K73 enables Hitachi to continue its technical edge in today's competitive landscape, while providing manufacturers the ability to construct more powerful storage systems. The Ultrastar 15K73 will be available in both Ultra 320 SCSI and 2 Gb FCAL FCAL Fibre Channel Arbitrated Loop interfaces in the first quarter of 2003. "Hitachi brings a much needed high-end storage alternative to customers with the new Ultrastar," said Dr. Fumio Kugiya, general manager, Server HDD (Hard Disk Drive) See hard disk and HDD caddy. HDD - hard disk drive Business Unit, Hitachi Global Storage Technologies. "The Ultrastar 15K73 represents an excellent solution for today's demanding applications such as SANs, NAS (1) See network access server. (2) (Network Attached Storage) A specialized file server that connects to the network. A NAS device contains a slimmed-down operating system and a file system and processes only I/O requests by supporting the popular , RAID, data mining, audio-visual, server and other high-end applications." The new drive's maximum sustained data transfer rate of 77.2 Mbytes/sec, combined with the high rotational speed, allows customers to access data more quickly and efficiently. The Ultrastar 15K73 is available in both 36 and 73 GB capacities. The drive's 1.2 million-MTBF specification meets the industry expectation for high reliability.
