Description
The HP 402523-B21 is an 18.2GB hard drive that utilizes the Wide Ultra2 SCSI interface. This interface was a significant advancement, offering improved performance and reliability over previous SCSI generations. The 'Wide' aspect refers to its ability to utilize a wider data bus (typically 16-bit or wider), which can double the potential data transfer rate compared to narrow SCSI configurations, although Ultra2 SCSI itself offers a maximum theoretical speed of 80MB/s. Operating at a spindle speed of 7200 RPM, this drive provides a moderate level of performance suitable for less demanding server roles or as a boot drive in older systems. While not as fast as higher RPM drives, it offers a good balance for applications that do not require the absolute highest I/O speeds, prioritizing stability and compatibility with existing infrastructure. This 3.5-inch drive is designed for integration into servers and storage systems that support the Ultra2 SCSI standard. It represents a reliable option for maintaining or upgrading systems that are not compatible with newer interfaces like SAS or SATA, ensuring continued operation for legacy hardware.
