Western Digital MAMR tech will allow 40+TB HDDs to be created

 

In the world of big data, capacity is everything, with hard drive manufacturers all over the world working on innovative ways to increase the storage density of hard drives to new heights. 
 
Western Digital, one of the world's top HDD manufacturers has revealed a new technology that should allow hard drives with capacities of 40+TB to be created by 2025, with the company planning to bring this technology to the datacenter as early as 2019. 
 
This new technology is called Microwave-Assisted Magnetic Recording (MAMR), which allows Western Digital to create drives that offer increased storage densities on hard disks without decreasing reliability, with the company planning to increase storage densities and cost of this technology by 15% per year. 

Many recent hard drive innovations, like the inclusion of helium in high capacity drives instead of standard air, have improved performance by decreasing air friction to increase reliability and to allow hard drive makers to fit more hard disks into each drive, rather than allow for increased capacities per hard disk. This new innovation will allow for increased storage densities per disk, which will have a huge impact on both pricing and capacity.  
 
 

MAMR is one of two energy-assisted technologies that Western Digital has been developing for years. The company recently innovated a breakthrough in material and process that provides the required reliable and predictable performance, as well as the manufacturability to accelerate areal density and cost improvements to an estimated average of 15 percent per year. Developments in the other energy-assisted technology, specifically, heat-assisted magnetic recording (HAMR), present new material science and reliability challenges that are not a factor in MAMR. Only MAMR demonstrates the reliability and cost profile that meets the demands of data center operators.


At the heart of the company's innovation breakthrough is the "spin torque oscillator" used to generate a microwave field that increases the ability to record data at ultra-high density without sacrificing reliability. Western Digital's innovative MAMR technology is expected to offer over 4 terabits-per-square-inch over time. With sustained improvements in recording density, MAMR promises to enable hard drives with 40TB of capacity and beyond by 2025, and continued expansion beyond that timeframe.

Today consumers can by Western Digital with capacities of up to 12TB at online retailers, making Western Digital's 40+TB claims for 2025 seem very ambitious. This would represent a storage density increase of over 3x over the next 8 years, which is a much faster rate of improvement than what we have seen in recent years (especially before Helium-filled drives became a thing).
