Year of new technologies and new volumes: Western Digital's MAMR goes into high gear

The world 's largest hard drive manufacturer joins its main competitor and promises us 16 terabyte models soon Which will ensure continued improvement in the field in the coming decade

After a few years in which we saw the PMR and SMR technologies dominate the mechanical drives market, it seems that this year the desired change will finally come - and the battle at the forefront of the world This will be between the HAMR and MAMR: a pair of similar advanced methods coming from the two largest manufacturers still in the business and designed to allow density And volumes we have not yet seen.

Seagate has promised us 16 terabyte drives based on Heat Assisted Magnetic Recording technology, a tiny laser used to heat points on the magnetic media prior to writing information (2018), and made a partial promise by stating that models Those from the EXOS family to the world of information centers are taking internal exams at the beginning of December - and now Has launched its own promise to launch new 16 terabyte drives based on Microwave Assisted Magnetic Recording (MAMR) technology, in which a micrometeorological component is responsible for the heating required to write information with precision and density that was previously impossible during 2019.

After we received from it a SMR drive with an innovative volume of 15 terabytes at the end of 2018 - Ready for the complete transition to the new age

Western Digital has publicly stated that it continues to invest resources In the HAMR technology, which was chosen by its central rival as the axis for the future of the market, even today, it seems that even professionals can not estimate the relative advantages and disadvantages of the two methods in mass production and commercialization. 18 terabyte during the coming year. This sounds especially promising, although we will be satisfied with the 16 terabytes that will be publicly available before we move on to the next obvious step.

It seems that There is a slight technological leadership in the transition to the use of technologies But it, too, has not yet begun to sell these models in practice, so that the situation may still turn over

For 2020, both companies that hold 90 together in the mechanical storage market seem to agree that 20 terabytes are the primary goal, still based on HAMR or MAMR - and combined with the use of a number of data reading heads to significantly improve sequential and random performance, Which we have already seen in practice on MACH.2 Over the past year.

The domain Has long since become the crowning glory - but it does not mean that there are no interesting developments in the old and secondary storage technology that accompanies us from the days of the first digital computers

What features on the hard drives will make you consider using them in the next few years, as opposed to using flash chips only? Let us share your reactions.
