Crucial MX500 M.2 SATA SSD Review (500GB)


ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

In ATTO we can see that the MX500 M2 easily exceeds its rated read and write speeds and actually was able to deliver 563MB/s read and 525MB/s write. We can see that there is a small hit to small file performance, however, this is mainly due to the new Spectre/Meltdown patch.


Crystal Disk Benchmark is used to measure read and write performance through a sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.


Similar to what we saw in ATTO, the MX500 M.2 is able to deliver over 563MB/s read and 525MB/s write speeds in Crystal Disk Mark. Taking a look at the 4K QD1 performance we can see the MX500 was able to reach 43MB/s read and just under 100MB/s write.


The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance. For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.

In AS SSD, the Crucial MX500 achieved an overall score of 1214 points. Sequential performance comes in at 528MB/s for read and 486MB/s for write. 4K QD 1 performance is about the same as before, only 4K read comes in at almost 40MB/s while 4K write comes in at 98MB/s. Additionally, we can see that during the AS SSD Copy test that the MX500 M.2 did fairly well with the ISO and game tests reaching almost the full bandwidth.


Anvil’s Storage Utilities (ASU) is the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.


Anvil Storage Utilities once again confirms all the performance numbers we have been seeing and overall, the Crucial MX500 M.2 achieved an overall score of 5,008 points.

    I know this is an old article, but I’m confused. The trimcheck screenshot literally says, “CONCLUSION: INDETERMINATE.” But the sentence below the screenshot says, “As can be seen in the screenshot above, TRIMcheck’s result is positive.”

    Can someone explain this to me?
