WD Gold 20TB Enterprise Class SATA HDD 3.5-inch 7200RPM

The Western Digital WD Gold 20TB Enterprise Class SATA HDD (WD201KRYZ-SP) is engineered for the demanding read/write cycles of always-on datacenter and enterprise server environments. Built on WD's OptiNAND technology, which integrates a flash-based iNAND device with the HDD architecture, this drive achieves 20TB capacity in a standard 3.5-inch form factor while maintaining the sustained reliability and performance characteristics required for continuous operation. The drive spins at 7200 RPM and is rated for up to 2.5 million hours mean time between failures (MTBF), reflecting its positioning as a mission-critical storage medium.

The WD Gold 20TB leverages Energy-Assisted Magnetic Recording (ePMR) technology to achieve high areal density without sacrificing data integrity. A 512MB DRAM cache buffer supports high-throughput sequential and random workloads, while the drive's vibration-sensing technology—Rotary Acceleration Feed Forward (RAFF)—compensates for multi-drive chassis vibration, a common performance degrader in rack-mounted server and NAS enclosures. With a workload rating of 550TB per year (TB/yr), it comfortably supports intensive enterprise applications that would exceed the rated limits of desktop or surveillance-class drives.

Designed for deployment across enterprise NAS systems, cloud storage infrastructure, AI training data repositories, and large-scale object storage platforms, the WD Gold 20TB is positioned as a high-endurance, high-capacity anchor drive for storage-dense configurations. Its compatibility with major enterprise server and storage platforms, combined with support for SATA 6 Gb/s interface, makes it a practical drop-in choice for environments standardized on SATA infrastructure seeking maximum per-bay capacity. Omnixon Global supplies this drive to enterprise and institutional buyers across UAE, GCC, EMEA, and APAC regions.

Ideal for

• High-density enterprise NAS and SAN arrays requiring maximum per-slot capacity for unstructured data repositories
• AI and machine learning training dataset storage where sustained read throughput and large sequential access patterns are critical
• Cloud and hyperscale object storage nodes demanding high workload endurance ratings and multi-drive vibration compensation
• Backup and recovery infrastructure where high capacity per drive reduces the total number of media targets in a tape-replacement or D2D2T architecture
• Media and entertainment post-production storage vaults handling large raw video files and high-resolution asset archives
• Enterprise surveillance and video analytics platforms requiring continuous write performance across extended retention periods
