16 TB NAS hard drive for multi-bay systems

This 16 TB WD Red Pro drive is built for RAID-optimised NAS enclosures with up to 24 bays. It targets businesses that need reliable 24×7 storage for archiving, file sharing and array rebuilding on file systems such as ZFS. The drive carries a 550 TB per year workload rating at a typical 40 °C operating temperature. It is suited for multi-user environments that demand continuous operation.

3.5″ SATA build with 7 200 RPM and 512 MB cache

The 3.5-inch form factor uses a SATA 6 Gb/s interface and spins at 7 200 RPM with a 512 MB cache buffer. Conventional magnetic recording ensures consistent write performance during heavy RAID workloads. Extensive vendor testing aims to deliver broad compatibility across NAS platforms. The mechanical design supports the vibration tolerance required in densely populated chassis.

Verify bay count, SATA ports

Confirm that your NAS enclosure supports 3.5-inch drives and provides enough drive bays for the intended RAID layout. Check that the backplane or controller offers sufficient SATA connections for each drive. Ensure the power supply can sustain the combined spin-up and running current of all installed units. Cooling must maintain the 40 °C typical temperature for the rated workload.

Questions about this item

What does the SATA 6 Gb/s interface mean for actual transfer speed?

The SATA 6 Gb/s interface sets the maximum data rate between the drive and the NAS controller.

What drive bay size is required for this 3.5" unit?

This is a 3.5 inch form factor drive, so it needs a standard 3.5 inch drive bay or a compatible mounting tray.

How is the drive installed in a NAS, and what step is often missed?

Mount the drive in the bay, connect the SATA data and power cables, then configure the RAID array in the NAS operating system before storing data.
