6TB Helium SAS Drive for Servers
The HGST Ultrastar He6 HUS726060ALS640 is a 6TB 3.5-inch internal hard drive built for server deployments. It uses a SAS 6Gb/s interface and spins at 7200 RPM with 64MB cache. The helium-filled design enables the industry-first 6TB capacity in the standard form factor.
SAS 6Gb/s Interface Limits
The SAS 6Gb/s link caps sustained throughput at the interface ceiling rather than the mechanical speed of the platters. Average seek time is 8.5ms. The drive fits standard 3.5-inch bays with maximum dimensions of 26.1mm height, 101.6mm width and 147mm length.
Upgrade from Lower-Capacity Air Drives
This drive replaces 3.5-inch air-filled enterprise drives below 6TB where rack density and power per terabyte matter. The helium platform reduces drag and heat, improving storage density in nearline and bulk-storage workloads. Buyers who need more than 6TB per spindle or a different interface will need a different model.

Questions about this item
Should I pick the 6TB helium-filled model or a smaller air-filled drive for my server?
The 6TB helium-filled Ultrastar He6 uses HelioSeal and 7Stac design to fit industry-first capacity in a standard 3.5-inch form factor, reducing power and cooling needs for high-density racks.
What does the 7200 RPM rating deliver in a real server workload?
7200 RPM with 64MB cache and 8.5ms average seek time provides consistent throughput for nearline and bulk-storage tiers in massive scale-out environments.
Will the SAS 6Gb/s interface bottleneck my HBA or backplane?
The SAS 6Gb/s link caps at 6 Gbit/s per port, so aggregate throughput depends on your controller lanes and backplane width rather than the drive itself.
