Today, we are reviewing the Crucial MX300 SSD in its largest 2 TB variant, which promises to provide tons of space for all your applications and games. Just like the MX300 750 GB we reviewed a while ago, it is built using Micron 3D TLC NAND, which is paired with a 4-channel 88SS1074 controller from Marvell.
In order to boost TLC chip performance to make up for the ground lost over MLC, Crucial designates a small, variably sized amount of memory as SLC cache, which writes a single bit to each TLC cell instead of every three. While much faster, such a setup is basically a speed vs. size tradeoff. In terms of technology, the SLC cache is identical to that of the MX200 (not BX200).
The MX300 Series is available in capacities of 275 GB, 525 GB, 750 GB, 1 TB, and 2 TB. Identically sized M.2 versions are available too, with similar performance, but that doesn't include the 2 TB version in this review.
