Capacity and Interface

The Western Digital Gold 2W10600 is an 18TB 3.5 inch internal hard drive with a SATA 6.0Gb/s interface and a 7200 RPM spindle speed. It uses Conventional Magnetic Recording technology and a helium-sealed design with 512MB cache. The drive is built for enterprise NAS, DAS, workstation and data centre server environments.

Who This Suits

It fits buyers who need high-capacity bulk storage for backup, archiving or big data workloads in systems that accept a 3.5 inch SATA drive. The Enhanced Vibration Protection and low power draw support multi-drive arrays and continuous operation. Builders who need a 2.5 inch form factor or a different interface should look at something else.

Deciding Specification

The single specification that decides fit is the SATA 6.0Gb/s interface combined with the 3.5 inch form factor; the motherboard or enclosure must provide a matching SATA data and power connection and physical 3.5 inch bay.

Questions about this item

What maintenance or replacement will the helium-sealed 18TB mechanism need over its service life?

The helium-sealed design has no user-serviceable parts; plan replacement when SMART attributes indicate wear or when capacity growth demands a larger drive.

Which limit appears first during sustained transfers on the 7200 RPM SATA 6.0Gb/s interface?

The SATA 6.0Gb/s link caps sustained throughput at 269 MB/s, so the interface is the bottleneck before the 512MB cache or spindle speed.

How much noise and heat does the low-power 3.5" enterprise drive produce in all-day operation?

Low power consumption and helium sealing keep acoustics and thermals modest; the drive runs cooler and quieter than air-filled equivalents under continuous load.
