Hitachi America Announces New Family of 10,000 RPM Disk Drives for Server, Network Storage Systems.BRISBANE, Calif.--(BUSINESS WIRE)--Oct. 28, 1999-- New Models Offer Up To 73.9 GigaByte Capacity, Fibre Channel and Ultra 160 SCSI Interfaces SCSI interface - SCSI adaptor Support Advanced Storage Network Applications Hitachi America, Ltd., a subsidiary of Hitachi, Ltd., (NYSE NYSE See: New York Stock Exchange :HIT), today announced a family of 10,000 RPM, ultra high-capacity, high-performance 3.5-in. disk drives for use in computer storage systems, including servers and storage area networks. With capacities reaching 73.9 GigaBytes (GB) and average data access rates in the range of 6 ms or less, the new drives reinforce Hitachi's position as a leader in applying the most advanced drive technology to production level products. Hitachi's latest 3.5-in. disk drive family includes three models; the DK31CJ-72 is a 73.9 GB, 41-mm (1.6-in.) height drive. The DK32CJ-36 and DK32CJ-18 offer 36.9 GB and 18.4 GB capacity, respectively, in a 25.4-mm (1-in.) height package. These exceptionally high capacities are made possible by incorporating proven, high-areal density technologies from Hitachi's market leading 2.5-in. drive products, including advanced Giant Magneto-Resistive heads and MEEPRML MEEPRML Modified Enhanced Extended Partial Response/Maximum Likelihood (hard drives) (Modified Extended Extended Partial Response Maximum Likelihood (storage) Partial Response Maximum Likelihood - (PRML) A method for converting the weak analog signal from the head of a magnetic disk drive into a digital signal. PRML attempts to correctly interpret even small changes in the analog signal, whereas peak detection relies on fixed ) read channels. These are Hitachi's first 10,000 RPM drives for the high-performance computer and storage systems OEM (Original Equipment Manufacturer) The rebranding of equipment and selling it. The term initially referred to the company that made the products (the "original" manufacturer), but eventually became widely used to refer to the organization that buys the products and and integration markets, which the company has served in the past with a line of high-capacity, 7200 RPM drives. Hitachi engineered the drives to achieve high rotation rates, and corresponding increase in data access speeds, while limiting power consumption to a range of 8.5 W (for the 18.4 GB model) to 15 W (for the 73.9 GB drive). Thus, the drives are suited for installation in both high-end workstations and server systems. Each of the drives is available with either the 100 MB/sec Fibre Channel interface, for storage area network and server farm installations, and the 160 MB/sec, Ultra 160 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. data storage system interface. "The tremendous growth of the Internet, particularly the e-commerce revolution and broadening use of database technologies, makes reliable and fast access to data mission-critical," said Gary Galusha vice president of hard disk drive sales and marketing for Hitachi America's Computer Division, Storage Products Group. "Hitachi's latest generation of high-capacity drives puts us in a great position to help satisfy the nearly insatiable demand for reliable, high-capacity storage products." In addition to the fast disk rotation rate, each of the new drives incorporates a 4 MB data buffer In computing, a buffer is a region of memory used to temporarily hold data while it is being moved from one place to another. Typically, the data is stored in a buffer as it is retrieved from an input device (such as a keyboard) or just before it is sent to an output device (such and use newly developed look ahead and write immediate cache algorithms This article is about general cache algorithms.

The 73.9 GB model, which is a 12 platter One of the disks in a hard disk drive. Each platter provides a top and bottom recording surface. There may be only one or several platters in a drive with each platter having its own pair of read/write heads. See magnetic disk. , 23 head drive, has an average read seek time of 5.7 ms and average write time of 6.5 ms. The two, 1-in. high drives achieve average read seek times of 5.2 ms and average write times of 6 ms. Average latency of each disk drive is just 2.99 ms. The new 3.5-in. drives are scheduled for sample release in the first quarter of 2000, with production ramp-up following in the second quarter.
