The next generation of hybrid storage drives is on its way - with an impressive starting volume of 20 terabytes and a dream to overcome the shortcomings of past attempts
Many factors have predicted the inevitable deaths of classic hard drives a few years ago, but in the meantime these products are still strong, kicking and relevant despite the steady decline in flash chip-based storage prices, with the understanding that there is more logical information to store on media Mechanics continues to permeate and spurs further investment in the development of hard drives Modern densities and more efficient.
Company Western Digital It is the one that provides us with the freshest update, as it says that it has started delivering to some of its customers first drives with an impressive 20 terabytes of volume, which are based on its new OptiNAND technology, which is designed to ensure continued volume growth while maintaining familiar performance and reliability levels. And even their upgrade.
WD decided to adopt the SanDisk technologies they acquired several years ago in order to integrate storage Flash from the iNAND family in the UFS standard (based on advanced 162D structures with XNUMX inner layers) in the new generation hard drives - no need to store some of the files that need frequent access as in previous generations of hard drives Hybrids that have not really managed to gain momentum, but in order to store important metadata that ensure more effective work of mechanical magnetic storage in a completely transparent manner to the user himself.
Storing bits in as dense circular channels as possible on hard disk drives is not an easy task, which is accompanied by quite a few unwanted physical effects that can disrupt the information and impair the operation of the entire array. WD's metadata makes it possible to map these problematic features on each drive, and its storage on modern media with fast access rates is designed to enhance all three leading features of a product. storage - Reliability, performance and also volume, thanks to the potential to compress even more magnetic bits in a given area without fear of the same mutual interference in question.
The first use of Western Digital OptiNAND technology comes in 20 terabyte drives for the world of servers and information centers, with nine helium-sealed rotating plates as part of the company's HelioSeal technology, with a record density of 2.2 terabytes per plate thanks to the use of the ePMR technique (RT Energy) its updated enhanced Perpendicular Magnetic Recording) and a state-of-the-art triple read-write head - but the company predicts the continued use of OptiNAND as part of the long-awaited transition to groundbreaking MAMR technology, with the goal of achieving up to 50 terabytes of 3.5-inch drive during the second half Of the current decade.
We hope that the American company's base on products NAND A "home" development will allow prices to be competitive even compared to standard PMR drives without OptiNAND soon - so that we can enjoy volumes of 20 terabytes or more in the home product series, as part of the ongoing wait for the breakthrough of next-generation technologies from WD and the competitor Seagate Which should help the possible volumes make an upward jump.
