The large image: As shoppers swap to solid-state drives for his or her velocity and reliability, producers maintain pushing spinning disk drives to carry capability greater and cost-per-gigabyte decrease. One flash provider believes it might handily outpace onerous drives over the subsequent few years.
Flash storage supplier Pure Storage told outlet Blocks & Recordsdata this week that it hopes to supply 300TB drives earlier than or by 2026. That might be a minimum of a six-fold enhance from its present 24TB and 48TB drives.
Pure Storage is optimistic relating to that tempo as a result of velocity of current 3D NAND developments. Final yr, Western Digital revealed plans to start manufacturing 162-layer NAND and attain over 200 layers by 2024. Micron began shipping 232-layer NAND final yr, whereas Samsung hopes to hit 1,000 layers by the shut of the last decade.
Alex McMullan, Pure Storage’s CTO, informed Blocks & Recordsdata that the corporate at present receives 112 and 160-layer NAND from its chip suppliers, they usually have plans to succeed in 400-500 layers over the subsequent few years, making ever-larger drives attainable.

Pure Storage shared a roadmap exhibiting the enlargement of DFM capability since 2012, steadily climbing till beginning a pointy incline round 2021. The corporate hopes that curve can maintain, bringing it to 300TB within the subsequent three years.
It additionally shared a chart illustrating its hopes that its merchandise’ Whole Value of Possession (TCO) will proceed falling in opposition to HDDs between now and 2027. The chart initiatives that HDDs will stay static on this space whereas flash buy costs may fall. Working flash storage is already cheaper than onerous disc storage.
Notably, Pure Storage’s projections fly previous these of firms specializing in high-capacity HDDs like Seagate. With HAMR know-how, Seagate plans to start out delivery 30TB HDDs this yr. The corporate hopes to hit 40TB by 2024 or 2025, 50TB by 2026, and 100TB by 2030.
