Micron's breakthrough technology enables world's first 2TB 22x30mm SSD optimized for client applications

BOISE, Idaho, January 24, 2022 – Micron Technology announced that the world’s first 176-layer QLC NAND SSD is now shipping in volume production, built on the most advanced NAND architecture for a wide range of provides industry-leading storage capacity and best-in-class performance for data-intensive applications. The new Micron 2400 SSD is the world's first 176-layer PCIe Gen4 QLC SSD built for client applications, based on Micron's revolutionary NAND technology designed for applications that span client and data center environments. The new 176-layer QLC NAND will also be integrated into some Micron Crucial consumer SSDs as a reference component for system designers.

Continuing the previously announced industry-first 176-layer TLC NAND, Micron's innovative 176-layer QLC NAND flash memory provides an unprecedented number of layers and capacities in QLC. Compared to the previous generation solution, the new 176-layer QLC NAND I/O throughput is increased by 33%[1], while read latency is reduced by up to 24%[2]. The Replacement Gate (RG) architecture it adopts is the only QLC NAND that combines the Charge Trap architecture and CuA (CMOS under the Array) design for mass production. These improvements will help accelerate the introduction of QLC SSDs in the client PC market, which is expected to triple the market share to over 35% by 2023 and nearly 80% by 2025. [3]

"Building on our leadership in 176-layer NAND, the Micron 2400 SSD will drive the client market transition to QLC storage," said Jeremy Werner, Micron's corporate vice president and general manager of the Storage Business Unit. "The new 2400 PCIe Gen4 SSD enables With wider design options and more affordable capacity, we expect it will significantly accelerate the adoption of QLC in client devices and further strengthen Micron's leadership in the market."

QLC NAND SSD for everyday computing

The Micron 2400 SSD provides industry-leading storage capacity among mainstream NVMe SSDs, enabling flexible OEM solution designs while delivering a great user experience. Combining 176-layer NAND and PCIe Gen4 technology, the series delivers double the performance and 23% faster read speeds than previous-generation Micron client SSDs, dramatically reducing boot and load times.

Micron's 2400 series SSD also includes the world's only 2TB 22x30mm M.2 SSD. Compared with the 22x80mm M.2 specification, the 22x30mm M.2 SSD reduces the footprint by 63%, which is perfectly suitable for small mobile notebooks and is designed for Provide more flexibility. In addition to the aforementioned sizes, the series is also available in two other sizes (22x42mm and 22x80mm M.2) and supports common firmware to drastically reduce design verification time.

Micron 2400 SSD uses the company's Host Memory Buffer technology (HMB, Host Memory Buffer), which enables the host to flexibly optimize performance and provide a powerful user experience in different cases. The product features low power consumption to support 24/7 unrestricted computing, and its active idle power consumption is reduced by 50% compared to previous Micron solutions. The Micron 2400 SSD was born to meet the needs of Intel's "Project Athena", enabling laptops with high-resolution displays to achieve more than 9 hours of actual battery life. [5]
