Product details

WD Gold is enterprise iron for people building serious local storage: workstations chewing on 4K timelines, deskside AI boxes, or a home server that earns its keep. This 10TB model spins at 7,200 RPM with a big 512MB cache, CMR recording, HelioSeal and OptiNAND technology, and transfers up to 267MB/s. WD rates it for 550TB/year workloads and up to 2.5M hours MTBF, with rotational-vibration sensors for multi-drive enclosures and a 5-year limited warranty. Overkill for a game folder - perfect for everything behind it.

WD Gold is what you buy when the data on the drive is worth more than the drive by orders of magnitude: a workstation's active project store, a deskside machine learning box chewing datasets, a video editor's working volume, or the core of a home server that other systems depend on. Ten terabytes at 7,200 RPM with a 512MB cache and transfers up to 267MB/s is the fast end of spinning storage, and the enterprise engineering — HelioSeal, OptiNAND and ArmorCache technology — exists to keep it that way under load.

The rating that defines the class is the workload figure: up to 550TB per year, several times what desktop drives are built to absorb, with rotational-vibration sensors for stable behavior in multi-drive enclosures. CMR recording keeps long writes honest during ingest, replication and backup windows. This is not the drive for a game folder; it is the drive for the systems the game folder gets backed up to.

Fitment is standard 3.5-inch SATA, so it drops into servers, NAS boxes and tower workstations alike, and a 5-year limited warranty matches the service life it was designed for. For storage that earns its keep every day, Gold is WD's answer — enterprise iron, honestly labeled.
