During Computex, Micron announced its first PCIe 4.0 SSDs using 176-layer NAND flash memory, the Micron 2450 series and the Micron 3400 series. Besides the new SSDs, it also showed the 1α-based LPDDR4x and DDR4 memory modules.
The Micron 2450 series will be available in three form factors: M.2-2280, M.2-2242, and M.2-2230. Available with 256GB, 512GB, and 1TB capacities, these SSDs are aimed at everyday computing and should be priced accordingly. Read speeds may go up to 3,600MB/s, while write speeds can “only” reach 3,000MB/s.
Unlike the 2450 SSD, the Micron 3400 SSDs are only available in the M.2-2280 size and with 512GB, 1TB, and 2TB storage capacities. With sequential reads reaching up to 6,600 MB/s and sequential writes up to 5,000 MB/s, these SSDs can accelerate workloads considerably even if you’re upgrading from a PCIe 3.0 SSD.
