Product Description
This HP hard drive, model D9476-63001, represents a robust storage solution from an era where SCSI was the dominant interface for high-performance enterprise storage. With a capacity of 18.2GB, it was suitable for operating systems, critical applications, and smaller datasets in server environments. The Ultra-160 SCSI interface is a key feature, offering a significant improvement over previous SCSI standards by doubling the transfer rate to 160MB/s through technologies like Wide Ultra3 SCSI. This interface is known for its reliability, command queuing capabilities, and support for multiple devices on a single bus. The drive operates at a spindle speed of 7200 RPM, which was considered a good balance between performance and thermal output for enterprise drives at the time. This rotational speed translates to a rotational latency of approximately 4.17 milliseconds, influencing the average seek time for data retrieval. The 3.5-inch form factor is standard for enterprise hard drives, designed to fit into server drive bays and hot-swap enclosures. These drives were typically built for 24/7 operation, emphasizing durability and consistent performance under heavy workloads. While its capacity is modest by today's standards, the D9476-63001 was a workhorse for its time, providing the speed and reliability demanded by servers and storage arrays. Its SCSI interface ensured robust connectivity and management features essential for enterprise IT infrastructure. This drive would have been commonly found in HP ProLiant servers and other enterprise-grade hardware requiring dependable internal storage.
