Micron 2400 SSDs are available in three sizes: M.2 2230, M.2 2242, and M.2 2280. It is also the only solution in the world that provides 2TB M.2 2230 SSD. At present, these SSDs have been shipped to OEM manufacturers for cost-effective desktop and notebook markets.
Micron introduces 2400 QLC SSDs
The 670p SSD launched by Intel last year has indeed changed the image of QLC SSD, and QLC flash memory is indeed slowly eroding the market of TLC flash memory, but this process is much slower than that when TLC replaced MLC. Recently, Micron announced the launch of the 2400 SSD, using the latest 176-layer QLC flash memory, using the PCI-E 4.0 interface, and the maximum read speed can reach 4500MB/s.
Micron’s 176-layer flash is put into production at the end of 2020, but there is no news of QLC flash before. Compared with Micron’s own 96-layer QLC flash, the new 176-layer QLC can provide an additional 33% I/O throughput and reduce 24% read latency. Micron 2400 SSDs are available in 512GB, 1TB, and 2TB capacities. The performance of different capacities is different. The best 2TB continuous read speed is 4500MB/s, the continuous write speed is 4000MB/s, and the random read and write speeds are 650K and 700K IOPS respectively. In terms of durability, the write volume is 150TBW per 512GB. Micron said that compared with the previous generation QLC SSD, the standby power consumption has been reduced by 50%.
