Product Description
The HP 3R-A4409-AA is a high-performance hard drive built on the Ultra-320 SCSI interface, representing one of the fastest SCSI standards available. It offers a capacity of 36.4GB and boasts an impressive rotational speed of 15000 RPM, ensuring minimal latency and rapid data access for demanding enterprise applications. The Ultra-320 standard doubles the throughput of its predecessor (Ultra-160), reaching theoretical speeds of up to 320 MB/s, and includes features like improved command queuing and CRC error checking for enhanced reliability and performance. This drive is designed for the rigors of enterprise environments, where uptime and data integrity are critical. The 15000 RPM speed is indicative of its focus on high-IOPS (Input/Output Operations Per Second) performance, making it suitable for boot drives, operating systems, or critical application data that requires the fastest possible access. The 8MB cache helps to buffer data and further optimize read/write operations. Utilizing the standard 3.5-inch form factor, this drive is compatible with a wide range of enterprise server chassis and SCSI RAID controllers. While Ultra-320 SCSI has been largely replaced by SAS and NVMe in modern infrastructure, drives like the HP 3R-A4409-AA were foundational for high-performance computing and storage solutions in their time, providing the speed and reliability needed for mission-critical business operations.
