Why Helium Matters: Helium has 1/7 the density of air. This reduces drag on the spinning platters and read/write heads, cutting power consumption by 23% and operating temperature significantly. HGST pioneered this technology in the Ultrastar He6 — the first 6TB drive in a 3.5" form factor, delivering 50% more capacity than competing 4TB drives while consuming less energy.

Server Compatibility: Fits 3.5" SAS drive bays in Dell, HPE, Supermicro, and other enterprise servers and storage arrays. Bare drive — caddy/tray sold separately.
