Motors & Drives Information

Hitachi Global Storage Technologies (Hitachi GST) today announced the Ultrastar 10K300, the world's first 300GB enterprise hard disk drive. Hitachi's newest 10,000 rpm hard drive satisfies the requirements of mission-critical storage applications such as online transaction processing, data analysis and media streaming. The new 3.5-inch drives have already begun shipping and are in the process of being qualified at major OEMs worldwide. Hitachi expects volume shipments of the Ultrastar 10K300 to begin in the second quarter of this year.

The Hitachi Ultrastar 10K300 is built on a proven drive design with demonstrated enterprise class reliability and product quality. The new drive continues this tradition with enhanced head and disk manufacturing processes designed to extend reliability and performance. The drives will use Fluid Dynamic Bearing motors to provide a low acoustic rating and improved data integrity.

Hitachi's time-to-market leadership and global technical support accelerates customers' qualification process, enabling products to be delivered to customers in a shorter amount of time. The capacity and performance characteristics of the Ultrastar 10K300 provide system builders the ability to deliver more powerful storage systems to their customers. The new drives will be available in Ultra 320 SCSI and 2Gb/s Fibre Channel (FCAL) interfaces.

"Being first to market with a 300GB server drive is a significant milestone," said Fumio Kugiya, general manager, Server Business Unit, Hitachi Global Storage Technologies. "Hitachi's technology expertise and product breadth are among the many reasons that customers are increasingly looking to Hitachi to meet their disk storage requirements. This is a significant achievement for Hitachi and is expected to solidify our position as one of the industry's top enterprise hard drive manufacturers."
