Overview

A helium-sealed 3.5-inch hard drive built for 24/7 NAS and RAID workloads. It delivers 20 TB capacity, 7200 RPM speed, and a 512 MB cache.

Helium-Sealed Design

The drive replaces internal air with helium to reduce turbulence and heat. This allows more platters in the standard 3.5-inch form factor while lowering operating temperature and power consumption.

NAS-Optimized Performance

NASware 3.0 firmware improves compatibility and integration with network storage systems. 3D Active Balance Plus controls vibration in multi-drive chassis to protect long-term reliability.

Continuous Operation Rating

Rated for 24/7 workloads with a 2.5 million hour MTBF. The 512 MB cache and 7200 RPM spindle sustain a 268 MB/s average transfer rate over the SATA 6G interface.

Power and Environmental Specs

Consumes 6.9 W during read/write, 3.8 W idle, and 1.6 W in standby. Operating temperature range is 0 to 65 degrees Celsius with 30 G shock resistance while running.
