Corsair’s new series enters above the currently still available MP300 with PCIe 3.0 x2 and the MP510 with PCIe 3.0 x4. The MP600 uses PCIe 4.0 x4 and thus reaches a maximum of around 5,000 MB/s.
In terms of storage capacities, Corsair’s new SSD series uses 3D-QLC-NAND of up to 8 TB in the M.2 form factor. The top-of-the-range models are to achieve transfer rates of 3,400 MB/s read and 3,000 MB/s write via PCIe 3.0 x4 when data is written in SLC mode.
What is new?
Especially in contrast to the MP510 with PCIe 3.0 x4 the memory has changed. With QLC-3D-NAND with four bits per memory cell the SSD gets more storage space and at the same time the costs are lower. However, in terms of performance, it is worse than the TLC-3D-NAND with three bits per cell. This also affects the durability. The differences are due to the controller, the MP300 does not use the Phison PS5012-E12, but only the smaller version PS5012-E12S, which accesses less DRAM cache. Hence the differences in performance...
