HDDs with very large capacities could be launched on the market soon.
I said a while ago that a company called HGST has launched the first helium hard drive with a capacity is used 10TB of storage PMR ( Perpendicular Magnetic Recording) technology, the last mentioned being the industry standard. The device has a height of only 25.4 millimeters, where HGST included no less than seven platters.
But according to the TrendFocus, quoted by website TechRadar, manufacturers of hard drives may soon produce models with higher storage capacities. By removing the various components that separate the platters between them, they will have enough space to include more platters. In these circumstances, the 3.5 inch hard drives could achieve in the near future capacities up to 18TB.
Of course, it would be initially available only to companies. In 2015, Samsung launched an SSD that provides enough storage space that you can copy it more than 3,800 movies in 720p resolution, of about 4.5GB each. Those who are willing to give up quality for quantity can put about 10,000 Xvid movies , the 1,5GB each , which would mean that , for two years , could run continuously each new film. The real capacity is 15,36TB, using between 480 and 500 256GB NAND flash modules. The SSD is standard size, that is 2.5 inches.
The density of helium is seven times smaller than air, so it significantly reduces friction discs and read and write head. This allows reduced force geared motor and mounting the disk platters closer together. Helium advantages do not stop there. In view of the low friction, operating temperature thereof is much smaller than the other models, and the noise is greatly reduced.
