Enterprise 8TB helium drive
The HGST Ultrastar He8 HUH728080AL4204 is an 8TB 3.5-inch internal hard drive built on a second-generation helium platform. It spins at 7200 RPM with a 128MB cache and connects through a SAS 12Gb/s interface. The bare drive targets enterprise and data-centre environments where capacity density and power efficiency are paramount.
Suited for high-density arrays, not desktop PCs
This drive fits servers, cloud and hyperscale storage, and distributed file systems such as Ceph and Hadoop that demand high capacity per slot and low watts per terabyte. It is not intended for consumer desktops or workstations that lack SAS controllers or 12Gb/s backplanes, nor for builds needing SATA-only connectivity without an adapter.
8TB capacity with efficient headroom
The helium design delivers 33% more capacity than 6TB air drives while cutting idle power by 23% and improving power efficiency by 44% in watts per terabyte. Average seek time is 8.5ms and average latency 4.16ms, supporting sustained throughput in scale-out deployments. Workloads requiring higher IOPS or sub-millisecond latency will exceed what this mechanical drive can provide.

Questions about this item
Does this 8TB SAS 12Gb/s drive need a SAS backplane or HBA to work in my server?
Yes, the HUH728080AL4204 uses a 12Gb/s SAS interface and must connect to a SAS controller or backplane; it will not operate on a SATA-only port.
Can I mix this helium-filled 7200 RPM drive with older 6TB air-filled drives in the same RAID array?
It fits the same 3.5-inch, 26.1mm-high bay and uses the SAS 12Gb/s interface, so it can share an array, though rebuild times will reflect the 8TB capacity and 8.5ms seek time.
How can I confirm the 128MB cache and 4.16ms average latency are active after installation?
Run the drive manufacturer's diagnostic utility or check SMART attributes; they will report the 128MB cache size and show latency figures consistent with the 4.16ms specification.
