Product Description
The Dell HC491 is a high-performance hard drive designed for servers and storage systems that utilize the Ultra320 SCSI interface. With a capacity of 146GB, it was a common choice for operating systems, critical applications, and databases in enterprise environments during its era. The 10,000 RPM rotational speed provides significantly faster data access and transfer rates compared to slower SCSI drives, making it suitable for demanding workloads. This drive utilizes a 68-pin connector, which is characteristic of Wide Ultra SCSI interfaces, allowing for higher data transfer speeds and bus widths. Ultra320 SCSI offers a maximum theoretical throughput of 320MB/s, providing a robust connection for high-demand applications. Its 3.5-inch form factor is standard for server-grade hard drives, ensuring compatibility with a wide range of chassis and drive bays. While SCSI technology is largely superseded by SAS and SATA in modern systems, drives like the HC491 remain essential for maintaining and upgrading legacy infrastructure. They offer a reliable solution for organizations that have not yet migrated their older SCSI-based systems. The 10,000 RPM speed ensures that even in an older interface, performance remains a key consideration for critical data access.
