After checking the performance of the Crucial MX500 4TB, we can clearly note that it works best as a secondary storage device, where speed is less of a priority, but the user will mainly be more interested in price per GB. The drive succeeds to maintain a rather high transfer speed even after the pSLC cache has been filled up thanks to the 176-layer TLC ICs, but also the DRAM for caching purposes. The use of TLC does also enhance the overall durability, the drive being guaranteed for 1PB of total writes during its lifetime.
