2400 SSD Billed as the most advanced NAND architecture

Micron has started volume shipments of the world's first 176-layer QLC NAND SSD.

Micron claims that its Micron 2400 SSD product is built with the most advanced NAND architecture and delivers the industry’s leading storage density and optimised performance for a broad range of data-rich applications.

The SSD is designed for use cases spanning client and data centre environments. 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 claims the QLC NAND enables 33 per cent higher I/O speed1 and 24 per cent 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 the adoption of QLC SSDs in the client PC market, which is expected to triple QLC adoption by 2023, exceeding 35 per cent, and reaching nearly 80 per cent bit share in 2025.3

Micron’s Storage Business Unit vice president Jeremy Werner said: "We expect the new 2400 PCIe Gen4 SSD will significantly accelerate the adoption of QLC in client devices as it enables broader design options and more affordable capacity."

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

The 2400 SSD is designed to meet Intel Project Athena requirements, enabling more than nine hours of real-world battery life on laptops even when using high-definition displays.
