California-based hard disk drive (HDD) manufacturer HGST has taken the next step in data storage volumes with the 10 terabyte HDD, the world’s largest volume yet.
Largely developed in Japan, the HDD was pioneered using helium gas as the medium for the device’s internal atmosphere.
HGST broke the 4 terabyte barrier for data storage in 2013 by filling the HDD itself with helium gas and sealing it in, launching the 6 terabyte HDD. It’s latest HDD succeeds the fellow helium-filled 8 terabyte HDD introduced in 2014, making it the third generation product in the series.
To understand the technology behind HDD’s is to understand the magnitude of this breakthrough itself. There are currently two commonly used types of HDD, one having a disk diameter of 3.5 inches – used in major servers and data centres for large data storage – and one thinner, lighter HDD having a disk diameter of 2.5 inches, used mainly for personal computers, Blu-ray/DVD recorders, and car navigation equipment.
