Micron Technology this week announced that it has begun mass shipping the world’s first solid-state drive that uses Micron’s 176-layer QLC NAND flash memory, also a world first.
The new memory is said to provide industry-leading storage density and optimized performance for a wide range of data-intensive applications. It is also suitable for servers, but the Micron 2400 drive in question belongs to the client segment. The company also announced that 176-layer QLC NAND memory will be used in select Micron Crucial consumer SSDs and shipped as components for use by other developers and manufacturers.
According to Micron, 176-layer QLC NAND memory outperforms previous-generation Micron memory by 33%. Read latency reduced by 24%. It is the only commercially available QLC flash memory that combines a charge trap architecture with CMOS logic under the cell array.
The Micron 2400 SSD is the world’s only M.2 2230 SSD with capacity up to 2TB. This drive is 63% smaller than current 2TB M.2 2280mm drives. It is equipped with a PCIe Gen4 interface and supports the NVMe 1.4 protocol.
The sequential read speed reaches 4500 MB / s, sequential write – 4000 MB / s. Performance on random access operations in read mode reaches 650,000 IOPS, in write mode – 700,000 IOPS. The line also includes 512 GB and 1 TB variants. All three are available in M.2 2242 and 2280 form factors. A 512 GB drive is 150 TBW, a 1 TB drive is 300 TBW, and a 2 TB drive is 600 TBW.
