WD Gold 3.5" 1TB, 7200 RPM, 128MB, 550 WRL, SATA III Hard Drive, Enterprise

The Western Digital WD1005FBYZ is a 1 TB enterprise-class hard drive engineered for high-demand storage environments such as data centers, servers, and workstations. It utilizes a 3.5-inch form factor and a Serial ATA III interface to ensure broad compatibility and reliable data transfer. Operating at 7200 RPM with a 128 MB cache, this drive is structured to handle sustained data throughput for mission-critical applications. Its design focuses on balancing performance with long-term operational stability and power efficiency.

This drive is built for continuous 24/7 operation and features a high workload rate limit and Mean Time Between Failures (MTBF) rating. Integrated Rotational Vibration (RV) sensors help maintain performance in multi-drive systems by counteracting vibration. It also incorporates end-to-end data protection and S.M.A.R.T. monitoring to support data integrity. The inclusion of SED security algorithms provides an additional layer of data protection for sensitive information.
