WD Red Pro 6TB 3.5" SATA drive

This enterprise-class hard drive delivers 6TB of storage on a SATA 6.0Gb/s interface. It spins at 7200 RPM with a 256MB cache and uses NASware 3.0 technology for error recovery. The 3.5-inch form factor fits standard desktop drive bays.

Suited for multi-bay NAS enclosures up to 24 bays

Designed for workloads up to 300TB per year with 3D Active Balance Plus vibration control. Builds needing higher throughput than SATA provides should consider other interface types. Systems limited to fewer drive bays or lighter workloads may not require this specification level.

SATA 6.0Gb/s interface determines compatibility

The drive connects via the SATA 6.0Gb/s standard, which sets the maximum host bus transfer rate. Confirm the controller or backplane supports this interface before purchase. No other interface option exists for this model.

Questions about this item

Will the 147.00mm length and 26.10mm height fit my 3.5-inch drive bay?

The drive measures 147.00mm long, 101.60mm wide and 26.10mm high, matching the standard 3.5-inch form factor used in most desktop chassis and NAS enclosures.

Do I need to change any jumper settings when installing the SATA 6.0Gb/s interface?

No jumpers are required; connect the SATA data and power cables, then initialise the 6TB volume in your operating system or NAS firmware.

How often should I check SMART data on a drive rated for 300TB per year?

Monitor SMART attributes monthly; the 5-year limited warranty covers the 7200 RPM mechanism and 256MB cache under the stated workload rating.
