The WD10EADS-00L5B1 is a 1TB Caviar Green 3.5-inch internal hard drive designed for energy-efficient desktop and NAS environments. Operating at 5400 RPM with a 32MB cache and SATA 3Gbps interface, it delivers sustained throughput suitable for sequential workloads while maintaining lower power consumption than 7200 RPM alternatives. The drive is compatible with standard desktop systems, small office servers, and external enclosures requiring 3.5-inch form factor drives. Typical applications include archival storage, backup targets, and capacity-dense storage arrays where performance is secondary to capacity and thermal efficiency.
