Description
The HP 313757-B21 is an 18.2GB hard drive that utilizes the Wide Ultra2 SCSI interface, specifically supporting LVD (Low Voltage Differential) signaling. Ultra2 SCSI represented a significant improvement in speed and cable length over previous SCSI generations, and LVD further enhanced signal integrity and performance, especially in longer cable runs common in server environments. The drive operates at a rotational speed of 7200 RPM, offering a balance of capacity and responsiveness for its time. This drive features a 3.5-inch form factor, typical for enterprise-grade hard drives, and includes a 1MB cache buffer. The cache helps to improve performance by temporarily storing frequently accessed data, reducing the need for repeated physical disk access. Its Wide SCSI implementation allows for a broader data path, further increasing transfer rates compared to narrow SCSI configurations. Designed for server applications, this drive is likely hot-pluggable, enabling maintenance and upgrades without system downtime. The combination of Wide Ultra2 SCSI LVD interface, 7200 RPM speed, and enterprise-class design makes the 313757-B21 a robust storage solution for servers and storage systems from the early to mid-2000s, providing reliable data storage and access.
