Micron Advances NAND Technology with 232-Layer QLC Production for Various Storage Solutions

Micron Technology, Inc. has achieved a significant milestone in NAND technology by initiating mass production of its 232-layer QLC NAND, now available in select Crucial SSDs. This advancement is also reaching enterprise storage customers through volume production and is being sampled by OEM PC manufacturers as part of the Micron 2500 NVMe SSD lineup. The new 232-layer QLC NAND by Micron is designed to enhance performance in multiple storage applications including mobile devices, client computers, edge technology, and data centers. This technology showcases notable improvements in efficiency and speed, featuring industry-leading bit density that achieves a 28% reduction in size compared to its closest competitors' most recent offerings. It also delivers a notable increase in NAND I/O speeds, reaching up to 2400 MT/s, which represents a 50% improvement over previous models.

Additionally, this technology offers a 24% enhancement in read performance and a 31% increase in programming performance relative to its predecessors. Bill Cerreta, the general manager of Hyperscale at Pure Storage, highlighted the impact of Micron's 232-layer QLC NAND, stating its crucial role in supporting Pure Storage's goal to phase out HDDs from data centers by 2028 through the use of their high-capacity DirectFlash Module. This innovation underscores Micron's leadership and commitment to advancing NAND technology.

There are three form factors: M.2 2280/2242/2230, and three capacity models: 512GB, 1TB, and 2TB. Transfer speeds vary depending on capacity; the 2TB model has sequential read 7,100MB/sec, write 6,000MB/sec, random read 1,000,000 IOPS, and write 1,000,000 IOPS, and the 1TB model has 7,100MB/sec, 5,800MB/sec, and 900,000 IOPS write. IOPS, 1,000,000 IOPS, 512GB model is 6,600MB/sec, 3,650MB/sec, 530,000 IOPS, 860,000 IOPS. The bus interface is PCI Express 4.0(x4)/NVMe 1.4c, the total write amount is 600TBW for 2TB, 300TBW for 1TB, 200TBW for 512GB, and MTTF is 2 million hours.
