WD Gold WD261KRYZ 26TB Enterprise SATA Internal Hard Drive

The WD Gold WD261KRYZ is a 26TB 3.5 inch internal SATA hard drive engineered for enterprise and commercial environments. Running at 7200RPM with a 512MB cache and transfer speeds up to 291MB/s, it handles heavy, continuous read-write workloads with HelioSeal technology and CMR recording for maximum data integrity.

Ideal for data centers, small and medium businesses, NAS systems, and design professionals who depend on mission-critical storage. Built on an 11-disk platform, the WD Gold excels in high-density server environments where sustained throughput, vibration resistance, and round-the-clock uptime are non-negotiable.

Backed by a 5-year limited warranty, a projected MTBF of 2.5 million hours, and an annualized failure rate of just 0.35%, the WD Gold represents Western Digital's flagship enterprise HDD line. ArmorCache technology provides power loss protection, while dual-sensor Rotational Vibration Safeguard (RVS) ensures consistent performance in multi-drive enclosures.
