Micron ships 176-Layer QLC NAND and unveils 2400 PCIe Gen4 Client SSD

Micron Technology has begun volume shipments of the world’s first 176-layer QLC NAND SSD — built with the most advanced NAND architecture.
Micron TechnologyMicron’s 176-layer QLC NAND delivers the industry’s leading storage density and optimized performance for a broad range of data-rich applications.

Designed for use cases spanning client and data center environments, Micron’s new NAND technology is now available with the introduction of the Micron 2400 SSD, the world’s first 176-layer PCIe Gen4 QLC SSD for client applications. The new 176-layer QLC NAND will also be incorporated into select Micron Crucial consumer SSDs, and available as a component for system designers.

Micron’s 176-layer QLC NAND provides a layer count and density unprecedented in QLC NAND flash and follows Micron’s delivery of the industry’s first 176-layer TLC NAND.

Micron’s 176-layer QLC NAND enables 33 percent higher I/O speed1 and 24 percent lower read latency than Micron’s prior generation solution. Its replacement-gate architecture is the only mass production QLC flash storage that combines charge trap with a CMOS-under-array design.

These improvements are driving adoption of QLC SSDs in the client PC market, which is expected to triple QLC adoption by 2023, exceeding 35 percent, and reaching nearly 80 percent bit share in 2025.

“Micron’s 2400 SSD builds upon our 176-layer NAND industry leadership to drive the transition to QLC-based storage for the client market,” said Jeremy Werner, corporate vice president and general manager of Micron’s Storage Business Unit. “We expect the 2400 PCIe Gen4 SSD will accelerate the adoption of QLC in client devices as it enables broader design options and more affordable capacity.”

The Micron 2400 SSD delivers industry-leading storage density in a mainstream, value NVMe SSD to enable flexible OEM solution design and provide an uncompromising user experience. With 176-layer NAND and PCIe Gen4 technologies combined, the 2400 SSD doubles the performance of Micron’s previous generation client SSD and delivers 23 percent faster read time for accelerated boot and load times.

Micron 2400 SSD is the world’s only 2TB 22x30mm M.2 SSD. This form factor shrinks the physical space required by 63 percent when compared with a 22x80mm M.2 form factor, providing design flexibility and making the drive ideal for small, mobile laptop designs. It is available in 22x42mm and 22x80mm M.2 form factors, all with common firmware to minimize design qualification efforts.

The 2400 SSD provides a robust user experience across diverse use cases enabled in part by Micron’s Host Memory Buffer technology that allows the host to flexibly optimize performance. The SSD features low-power consumption for all-day, untethered computing, with active idle power being reduced by 50 percent from Micron’s previous generation solution.
