Micron announces its new M.2 2400 SSD with capacities of 512 GB, 1 TB and 2 TB, but above all a miniature format of 22 x 30 mm, a space saving of 63% compared to the current 22 x 80 format mm, as shown in the picture below.
This type of format is ideal for laptop manufacturers who want to make their machines even more compact, or even for very small desktops.
To achieve this level of miniaturization, Micron used a new type of NAND flash memory QLC (four data bits per cell) with 176 layers of transistors. The manufacturer has thus gone from 96 layers to 128 layers, to now reach 176 layers. This technology is also available on TLC flash memory (three bits per cell), which is more expensive.
Equipped with a PCIe Gen4 interface, the 2400 2TB SSD offers maximum speeds of 4500MB / s read and 4000MB / s write. It also incorporates AES 256-bit hardware encryption. Micron guarantees an endurance of 600TB Written (TBW) over the life of the SSD.

Finally, Micron says the 2400 SSD consumes 50% less standby power than the previous generation of QLC models. It is compatible with Intel EVO specifications, for laptops offering at least 9 hours of battery life. The manufacturer has not disclosed the prices of this miniature SSD.
