In June of 2021, Micron updated its OEM and automotive SSD portfolio based on 176-layer NAND technologies. The Micron 2450 is a value SSD that leverages QLC NAND while the Micron 3400 SSD is designed to give system builders a performance-oriented drive with TLC NAND. Micron didn't sample either drive for review, but now that they are appearing to show up in OEM systems, we've been able to get hands-on with the 3400.
