300 TB SSDs Could Arrive as Soon as 2026, Claims Pure Storage

Pure Storage, a maker of various storage solutions and custom enterprise-grade SSDs, claims the company will produce SSDs with up to 300 TBs of capacity by 2026. In an interview with Pure Storage CTO Alex McMullan, Blocks & Files got exclusive information that the company targets SSD capacities of up to 300 TBs in 2026. Pure Storage creates proprietary Direct Flash Modules (DFM) SSDs which use 3D NAND chips controlled by a custom SSD controller, are used in the FlashArray systems, and run on a custom FlashBlade operating system. This level of customization allows Pure Storage to create SSD drives with remarkable capacities in the future as the 3D NAND technology advances.

In the coming years, 3D NAND flash manufacturers will switch from the current 200-layer chips to the 400/500-layer chips, driving storage density to new highs. As manufacturers update their technology, so does Pure with its DFM cards that use regular U.2 NVMe connectors in a custom ruler-style format made explicitly for Pure FlashArray systems. Compared to upcoming HDDs that Toshiba and Seagate will use, Pure Storage DFM SSDs will have much higher capacities and read/write speeds, especially as higher-density 3D NAND arrives. You can see the comparison of Pure’s estimates for the future 300 TB SSDs with future HDD technology.
