Product Description
The HP C2490A012520 is a hard disk drive designed for older server and workstation systems that utilize SCSI interfaces. With a capacity of 2.1GB and a spindle speed of 5400 RPM, it was considered a standard storage solution during its era. The drive employs an Ultra Wide SCSI interface, which allows for a 16-bit data path, offering improved performance over standard SCSI, though it is limited by the 5400 RPM rotational speed. The specific interface mentioned, 'Single-Ended Narrow 50-Pin', indicates the type of SCSI connector and signaling used. Single-ended (SE) SCSI is susceptible to noise over longer cable lengths compared to differential SCSI, and 'Narrow' refers to the 8-bit data path, which is somewhat contradictory to 'Wide' but often refers to the connector type. The 50-pin connector is standard for many SCSI devices. This configuration suggests compatibility with older SCSI controllers and cabling. This 3.5-inch drive is built for the rigors of server environments, though its capacity and speed are significantly lower than modern drives. It represents a legacy component suitable for maintaining or restoring older systems that rely on this specific type of SCSI connectivity and storage capacity.
