Enterprise helium drive

The HGST Ultrastar He8 0F23267 is an 8TB 3.5-inch internal hard drive built for 24x7 enterprise storage. Its helium-filled platform reduces turbulence and power draw per terabyte in data centre, cloud and hyper-scale deployments. The SATA 6.0Gb/s interface connects directly to standard server backplanes.

128MB cache and 512e format

A 128MB buffer smooths burst workloads while the 512e sector format maintains compatibility with legacy operating systems and RAID controllers. The Instant Secure Erase feature enables rapid sanitisation when drives are retired or repurposed. Bare-drive packaging means no cables or mounting hardware are included.

3.5-inch form factor with standard SATA connectors

Dimensions of 147.00mm width, 101.60mm height and 26.10mm length fit regular enterprise drive bays. Dual SATA data and power connectors face the rear for straightforward hot-swap tray insertion. The 7200 RPM spindle delivers 8.9ms average seek and 4.16ms average latency for consistent throughput. Not suited for desktop users needing bundled installation kits or consumer warranty support.

Questions about this item

Does the helium-sealed 8TB drive require any periodic gas refill or seal maintenance during its service life?

The helium platform is hermetically sealed at the factory and needs no gas refill or seal maintenance for the life of the drive.

What is the first performance limit reached when the Ultrastar He8 runs sustained 7200 RPM write workloads?

The 128MB cache and 6.0Gb/s SATA link set the sustained throughput ceiling before the mechanical 8.9ms seek time becomes the bottleneck.

How much heat and noise does the 3.5-inch helium drive produce when operating continuously in a 24×7 array?

Helium reduces internal drag, so the drive runs cooler and quieter than air-filled equivalents during all-day operation.
