Crucial MX500 4TB 3D NAND SATA 2.5-inch 7mm SSD Review

Storage/SSD by stefan @ 2023-09-24

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.

Drive Behavior during Continuous Write

In order to continue with the second stage of the tests, we needed to fill up the drive over 50%, while writing continuously to it. In IDLE, the drive has reported excellent temperatures:

The starting write speed was good as well:

After writing about 130GB, the speed remained about the same:

The controller temperature reached 42 degrees Celsius:

433GB written and we still got good transfer speeds:

The controller temp has reached 46 degrees Celsius:

After having written about 600GB, the transfer speed has lowered to about 330-350MB/s:

The controller temperature dropped a bit during this stage:

After a while, the speed has recovered:

The controller temp has jumped to 45 degrees Celsius:

Even after writing about 2TB of data, the speed rarely dropped under 400MB/s:

The maximum controller temperature we have noted was 46 degrees Celsius:
