Micron Delivers 176-layer NAND and 1α (1-alpha) DRAM Technology
Micron, the US-based manufacturer of various kinds of memory technologies, has today announced some quite interesting products at its Computex 2021 keynote. For starters, the company has announced a new portfolio of products based on 176-layer NAND. There are currently two products listed that use this new technology and those are the Micron 3400 and 2450 M.2 NVMe SSDs. Based on the PCIe 4.0 interface, the 2450 SSD lineup is designed as a value-oriented solution that comes in M.2-2280, M.2-2242, and M.2-2230 sizes. It ranges from 256 GB to 1 TB in capacities, which are supposed to be priced as a value purchase.
In a contrast, the 3400 SSD is M.2-2280 design, meant for only the highest performance. The sequential read speeds go up to 6600 MB/s, while the sequential writes go up to 5000 MB/s (in the case of the 2 TB model). Capacities range from 512 GB to 2 TB and only the 1 TB and 2 TB variants have the 5000 MB/s write speeds, while the 512 GB version is capped at 3600 MB/s speed. Both SSD models are featuring a heat spreader on top of NAND chips and spot an in-house and Micron-developed NVMe 1.4 SSD controller. However, Micron does note that the company is free to use any 3rd party SSD controller as we are deep in component shortages with high demand for SSDs. You can get an in-depth look at the 2450 and 3400 M.2 SSDs from Micron's website.
