HGST fill their hard drives with helium: More capacity and greater energy efficiency
A hard drive has traditional dishes. More than one plate, most of the time, that adding capacity, give the total disk. What’s in between those dishes? Air, of course. That is, until now. Because HGST, company formerly Division Hitachi Hard Drives and is now owned by Western Digital announced that they are developing hard drives that are inside Helium instead of air.
What’s the point? According HGST, this allows greater storage capacities and better energy efficiency than traditional air discs. Because the current system, to not worry too much air aspect, which is not really pure air at 100%, it causes some turbulence inside where the disks spin at over seven thousand revolutions most cases.
HGST is why we decided to completely seal the records and fill them with helium. The result? A 23% improvement in energy efficiency as well as better manage internal pressure to introduce more courses in the same space, increasing the amount of GB that can be put into a single 3.5 inch drive, adding two dishes.
This last point is something mysterious and complex to explain, so HGST parliament was spared and only said what he did and what it was used this technique. And it is said, it took no less than six years to develop the technology, which is also inexpensive to deploy en masse, so it will be available in the general market as soon as next year 2013.air, dish, dishes, disk-drive, Hard Drives, Helium, HGST, WD, Western Digital
