Crystal Disk Benchmark is used to measure read and write performance through 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.
In Crystal Disk Mark the MX300 was able to reach 535MB/s read and 512MB/s write during the sequential tests. 4K read and write results are decent, reaching 31MB/s read and 148MB/s write. We would have liked to see a bigger improvement at this smaller file size considering the Samsung 850 EVO reaches over 50MB/s read at 4K.
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 MX300 attained an overall score of 1138 points. Sequential speeds reach 494MB/s read and 488MB/s write. 4K read reached just under 30MB/s read and 127MB/s write, which is an average result. Furthermore, it hit 91K IOPS read and 75K IOPS write. During the copy test it did well too, with a best transfer speed of 421MB/s in the Game copy portion.
ANVIL STORAGE UTILITIES PROFESSIONAL
Anvil’s Storage Utilities (ASU) are 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.
Finally, in Anvil we see that the performance is in line with what we have seen in the other tests. Overall, the MX300 reached a total score of 4,863 points. Let’s continue on and see how these drives handle our more realistic PCMark test suites.
