Western Digital Caviar SE 40GB hard drive (part No. WD400BB-18DEA0) features a 3.5-inch form factor with 7200 RPM spindle speed and 2MB cache buffer for improved performance in desktop and small office environments. The ATA-100 (PATA/IDE) interface provides up to 100 MB/s throughput and is compatible with legacy systems and workstations built before the transition to SATA. This drive is suitable for archival storage, secondary backup, or integration into older server and workstation builds where parallel ATA remains the standard. Typical applications include non-critical data retention, test environments, and system rebuilds requiring period-appropriate components.
