The reads like a fluff piece that just doesn't add up. Dropbox mentions testing 14TB SMR drives in the post from June 12 2018 https://www.anandtech.com/show/15457/western-digital-roadmap-updates-energy-assisted-recording-multistage-actuators-zoned-storage https://www.anandtech.com/show/15457/western-digital-roadmap... . If I have a look on Amazon right now, the largest HDDs are 16TB CMR drives, not SMR. Anandtech has a post based off of WD's press release from December 23rd 2019 here https://www.anandtech.com/show/15457/western-digital-roadmap-updates-energy-assisted-recording-multistage-actuators-zoned-storage https://www.anandtech.com/show/15457/western-digital-roadmap... . The energy assisted MAMR drive is 18TB in capacity, while the SMR drive is 20TB in capacity. Where's the 25% capacity benefit? Shouldn't the SMR drive offer a capacity of 22.5TB? Have a look at this https://www.anandtech.com/show/15457/western-digital-roadmap-updates-energy-assisted-recording-multistage-actuators-zoned-storage https://www.anandtech.com/show/15457/western-digital-roadmap... article at Anandtech posted January 31st 2020. Note the side by side comparisons of projected growth of SMR drive capacity shipments. SMR growth projections are always right around the corner in the next 1-2 years. Why is this? Quite simply the market doesn't want SMR. Non-SMR technology continues to improve, eliminating SMR's capacity advantage after a period of time without SMR's orders of magnitude performance penalties. If SMR was more than just a one time 25% capacity advantage it might be worth buying into. But it doesn't. It's a technology in search of a market that just doesn't exist because of all the downsides. HAMR and MAMR are the promising technologies to increase HDD capacity, not SMR.
