HGST Ultrastar He8 0F23669 6TB 7200 RPM 128MB SATA 6.0Gb/s 3.5" internal hard drive

Enterprise Capacity Drive

The HGST Ultrastar He8 0F23669 is a 6TB 3.5-inch internal hard drive built for continuous operation in servers and NAS systems. It spins at 7200 RPM with a 128MB cache and connects through a SATA 6.0Gb/s interface. HelioSeal technology replaces air with helium to reduce turbulence and enable a seven-disk design inside the standard form factor.

Workload Fit

This drive suits environments that prioritise capacity density and power efficiency over access latency, such as cloud storage tiers, hyperscale archives and large-scale RAID arrays. The 2.5M hour MTBF and 0.35% AFR ratings reflect design targets for 24x7 duty cycles. Buyers who need sub-millisecond response times or the throughput of a solid-state interface should look at alternative storage classes.

Deciding Specification

The SATA 6.0Gb/s interface determines whether this unit can drop into the target backplane or controller without an adapter. It also caps the maximum sustained transfer rate to the bus limit, so the drive will not saturate faster interconnects. Verify that the host system expects a 512e advanced-format SATA device before purchasing.
