The Ultrastar Archive Ha10 is the company’s latest version of a helium-based HDD. The apparent benefits of helium when it comes to HDD storage is its considerably lower density which is around 1/7 that of regular air. This means less friction with internal moving parts, resulting in less power needed to drive the device and increased data density of the individual disks.
HGST calls its version of this hard drive The HelioSeal and has combined it with shingled magnetic recording (SMR), a hard drive technology that records data on overlapping tracks, much like roof shingles. The company says this results in an industry-leading storage density, low power consumption and very reliable storage solution. However, since SMR requires the writing of entire tracks, the drive is suited for active archive duties rather than frequent update workloads.
It comes in SATA 6 Gbps and SAS Gbps varieties and HGST claims a 20 percent improvement in Watts per TB over the preceding Ultrastar He8.
To begin with, the Ultrastar Archive Ha10 will be available to cloud and OEM storage clients with the software capabilities to harness the density of the device.
