This just adds fuel to the fire that HAMR technology is not ready for prime time, and neither is this R&D grasping at straws for a releaseable product in less than 2 years.. at which time the 7 BILLION DOLLAR chip plant samsung is building will be making 10nm flash chips capable of superceding all current hard drive technology in FLASH SSD!! So, the hard drive industy is really at a crossroads.. either gamble on HAMR technology & pony up the 5 billion to build a plant OR seek financing to go TOE TO TOE with the 10nm chip process and just make SSDs... all of which WILL be more expensive at first, so.. $450 4tb SSD drives are not out of the question (at least the ones that can get 500 - 700MB/second transfer rate). We'll expect drives to be made which are "SLOWER" in the range of 125mb to 250mb to be about half price... as this will be more reasonable and able to pay off the R&D cost over 5 years..
BTW, there is massive rampant speculation on which way the hard drive companies will go.. besides, if HAMR hard drives are going to be upto 40% more expensive to make going forward.. is it really worth it? The only glitch in going SSD is there will be competition beyond the current hard drive companies so that could create competitive problems for companies who only know hard drives. The consumer doesn't care who gets there first at a cheaper price & highest quality.
Promises of 6 - 40TB hard drives with HAMR technology are just that promises.. there's nothing that says flash chips can't achieve the same densities in the 10nm process at speeds and reliability that put HAMR to shame. Only R&D can tell which path is worth the gamble.
