The Western Digital Caviar Green 640GB (part no. WD6400AACS-00G8B1) is a 3.5-inch SATA hard drive designed for low-power, high-capacity storage in desktop and external enclosure applications. Spinning at 5400 RPM with a 16MB cache and 3Gb/s interface, this drive delivers sequential throughput suitable for archival, backup, and general-purpose file storage workloads where performance is secondary to capacity and energy efficiency. Compatible with standard SATA connections found in most servers, NAS systems, and external storage arrays, the Caviar Green operates at reduced power consumption compared to 7200 RPM alternatives, making it cost-effective for 24/7 deployment in non-performance-critical environments. Typical applications include cold storage tiers, backup repositories, and media libraries.
