What hard drives are helium-filled?
What hard drives are helium-filled?
Currently, both Seagate and Western Digital manufacture helium-based hard drives. Seagate was also sitting at the top of this market with drives that have a capacity of 16 TB, that is until Western Digital shocked the market with it’s 20TB Data center hard drive.
Are helium-filled hard drives better?
Being seven times lighter than air, helium creates less drag and turbulence when HDD platters spin. It runs at cooler temperatures, and when sealed, it keeps out humidity. All those benefits translate to dramatically increased data storage capacity, lower power draw, and better reliability.
Which WD drives are helium-filled?
The 10TB He10 drive was rebranded as the DC HC510. It is a helium-filled drive with seven platters, 1.428GB/platter and an 816Gbit/sq in areal density. In contrast, the HC330 has six platters, 1.666GB/platter and an 868 Gbit/sq in areal density. This is 6.4 per cent more than the HC510.
How long do helium-filled drives last?
5 years
Ensuring that the helium stays sealed inside the HDDs for 5 years—the life-span of a hard disk drive—proved to be a particularly difficult challenge.
Are helium hard drives worth it?
Performance and Reliability I’ll admit that the performance of helium hard drives is a bit better than air-filled hard drives, but they are ahead by just a small fraction. The difference between them is nothing that the average user would be able to take much of an advantage of.
Why is helium used in HDD?
A helium drive is a hard disk that exploits the characteristic lightness of that gas to increase the medium’s potential speed and storage density. Potential speed and density are increased because helium, which is less dense than air, creates less drag and turbulence.
Is WD Red Pro helium?
Mechanically, the Western Digital Red Pro WD141KFGX 14TB is a 7,200 RPM drive with eight high density platters inside. The drive is helium filled for reduced resistance, which means more platters can be stacked in the same amount of space along with reduced power consumption.
Are WD gold helium filled?
The Gold disks are good for NAS and general purpose storage. They are helium filled and are perpendicular recorded for good performance.
Do helium drives leak?
Hard drives have not been able to be hermetically sealed with existing technology so that helium will gradually leak out and while atmospheric pressure will eventually cause air to leak inside, Xyratex wrote. Helium poses another long-term potential problem in terms of availability.
