Micron announces the industry’s first SSD with 176-layer 3D TLC NAND flash memory
Micron announced the launch of two new SSDs using the industry’s first 176-layer 3D TLC NAND flash memory chips, the 2450 series, and the 3400 series, both of which support PCI-E 4.0 to target different types of PCs and markets. Micron said that these SSDs are in production and will soon appear in the retail market.
The 2450 series SSD is aimed at the mainstream PC market. It provides M.2 2280/2242/2230 in three different form factors and provides three capacities of 256GB, 512GB, and 1TB. The sequential read and write speeds of the 256GB version are 3600MB/s and 1600MB/s, and the 4K random read and write are 190000 and 400000 IOPS respectively.
The sequential read and write speeds of the 512GB and 1TB versions are 3600MB/s and 3000MB/s, respectively. The former 4K random read and write are 380,000 and 500,000 IOPS, and the latter 4K random read and write are 450,000 and 500,000 IOPS, respectively.
Micron stated that the 2450 series and 3400 series SSDs use a self-developed main control chip that supports NVMe 1.4, but the configuration can be more flexible. If necessary, a third-party main control chip can be used.
