Micron has started shipping 176-layer QLC NAND flash SSDs. New items offer read speeds of up to 4500MB / s. The company says the Micron 2400 drives will be the first in the industry to use 176-layer QLC chips.
Micron released 176-layer MLC chips in late 2020, but the introduction of similar technology in the production of QLC memories will make it possible to offer large-capacity SSDs at a cheaper price. The new Micron 2400 PCIe 4.0 NVMe SSDs are already being shipped to consumer PC manufacturers, so users will soon be able to experience the new products first hand.
It is noteworthy that Micron offers its customers the 2400 drive in a tiny M.2 form factor of 22 x 30 mm. The novelty is one of the smallest among the existing 2TB drives. The Micron 2400 will also be available in 22x42mm and 22x80mm form factors.
Compared to Micron’s 96-layer QLCs, their 176-layer successors offer 33% more I / O bandwidth and 24% less read latency. In terms of storage capacity, the Micron 2400 will be available in 512 GB, 1 TB and 2 TB versions. The maximum capacity models offer sequential read and write performance of 4500 MB / s and 4000 MB / s, respectively. IOPS (input / output operations per second) reach 650 thousand for random read and 700 thousand for random write.
In terms of resources, Micron lists up to 600TB of storage for a 2TB drive. For the 512 GB model, the write resource is declared as 150 TB. The power consumption of the new products in idle mode has been reduced by 50% compared to the previous generation.
It goes without saying that SSDs with 176-layer QLC chips are primarily geared towards the budget segment. Their performance is far from the fastest consumer drives that can reach speeds of 7000 MB / s. However, such a speed gap should be more than made up by the cost of new products.
