First 176-layer QLC NAND SSD begins volume shipment

13 January 2022

Micron Technology Inc. has begun volume shipments of what it claims is the world’s first 176-layer QLC NAND solid state drive (SSD).

The 176-layer QLC NAND features storage density and performance for a range of data applications and is available with the introduction of the Micron 2400 SSD, the first 175-layer PCIe Gen4 QLC SSD for client applications.

The SSD enables 33% higher I/O speed and 24% lower read latency than Micron’s prior generation SSD. The replacement gate architecture is the only mass production QLC flash storage that combines charge trap with a CMOS-under-array design, the company said.

QLC SSDs are expected to triple QLC adoption by 2023, exceeding 35% by that time and reaching nearly 80%-bit share by 2025, according to market analysis from SSD Insights.

The Micron 2400 SSD doubles the performance of the previous generation client SSD and delivers 23% faster read time for accelerated boot and load times. The solid-state drive features low power consumption for all-day, untethered computing with a reduction of 50% power from Micron’s previous generation SSD.
