HGST delivers first-10TB HDD with helium from




WD has started delivery of the HA10 HGST drives with 10TB storage. The disks oriented enterprise applications are filled with helium, rather than with air. This gives the platters and heads suffer less friction.

HGST logo The first discs filled with helium supplies HGST since November 2013. That first version was a 6TB and 8TB later. HGST, part of Western Digital supplies these second generation helium-filled discs under the name Ultrastar Archive HA10 SMR hdd.

It is the first disc of the company that uses SMR, either shingled magnetic recording. SMR is a way of storing data on magnetic tracks which are slightly overlapping each other, whereby the density data is larger. A write head of a magnetic disk makes narrow tracks less than a read head can read, so that there may be a small overlap between the adjacent tracks. The disadvantage is that performance by SMR something go down, but for the purpose for which the disks are made is probably not a problem.

The main market where HGST is focusing on the discs, especially businesses that need to archive large amounts of data, which according to the company still mostly sequential data is stored and read rather than random. The 3.5 “drive rotates at 7200rpm, has seven platters, a 6Gbps / s SAS interface and 256MB cache

HGST delivers via Github an open source SDK to facilitate application development and deployment with new smr command set for Linux. Prices are on request.
