Frequently Asked Questions

Is the Gold 4TB SATA compatible with my NAS?

Yes, the WD Gold 4TB SATA uses a standard SATA 6Gb/s interface and 3.5" form factor, compatible with any NAS that accepts 3.5" SATA drives. It is widely supported by Synology, QNAP, TrueNAS, and Unraid systems. The 550 TB/year workload rating makes it suitable for always-on NAS environments.

Can I use the Gold 4TB SATA in a RAID array?

Yes. The WD Gold 4TB SATA is designed for RAID deployments. Its 550 TB/year workload rating and 2,500,000 hours MTBF ensure reliability in RAID 5, RAID 6, RAID 10, and ZFS configurations. Enterprise and NAS drives include error recovery features (TLER/ERC) for RAID controller compatibility.

What does the 550 TB/year workload rating mean?

The workload rating indicates the maximum annual data transfer the drive supports while maintaining stated reliability. 550 TB/year means the drive supports approximately 1.5 TB of data transfer per day, suitable for busy file servers and multi-user environments.

How fast is the Gold 4TB SATA?

The WD Gold 4TB SATA spins at 7,200 RPM with a 256 MB cache buffer, delivering sustained transfer rates up to 255 MB/s. This is optimal for sequential workloads like large file transfers and backup operations.

How much power does the Gold 4TB SATA consume?

The WD Gold 4TB SATA draws 8.8W under operating load and 5.7W at idle. For multi-drive configurations, factor these values into your power budget — a 12-drive array would consume approximately 106W under load.
