Helium-sealed 6 TB enterprise drive spins at 7200 RPM with 128 MB cache and SATA 6.0 Gb/s interface
The HGST Ultrastar He8 HUH728060ALE600 is a 6TB 3.5-inch internal hard drive built for enterprise storage arrays and servers. It spins at 7200 RPM with a 128MB cache and uses a helium-sealed HelioSeal design to deliver high capacity with lower power draw per terabyte. The SATA 6.0Gb/s interface supports standard hot-swap bays and backplanes.
Verify that your system provides a free SATA 6.0Gb/s port and a standard 3.5-inch drive bay with 26.10mm height clearance. The bare-drive packaging means no screws, cables or mounting brackets are included. Confirm your RAID controller or host bus adapter supports 6TB drives and the 512e or 4Kn advanced format used by this model.
This drive upgrades from lower-capacity 7200 RPM enterprise SATA units where rack space and power budgets are tight. The helium platform cuts watts per terabyte, so the jump is worth it when you need more raw capacity in the same slot count. It is not suited for desktop workloads that demand low acoustic noise or consumer warranty terms.

The drive is supplied as a bare unit only; SATA data and power cables plus any 3.5" mounting hardware must be sourced separately.
Choose the 4Kn model for native 4 KB sector operation; select 512e only if the operating system or RAID controller requires 512-byte emulation.
The 7200 RPM platters and 128 MB cache deliver sequential reads and writes near the SATA 6.0 Gb/s ceiling, with average seek of 8.5 ms and latency of 4.16 ms.
