Crucial MX300 SSD Review (750GB)

CRYSTAL DISK BENCHMARK VER. 4.0.3 X64

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.

AS SSD BENCHMARK VER 1.8

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.

There is a typo in the first page where you say that the mx300 has mlc nand, and some photos won’t zoom in. Otherwise good review.

Thanks for pointing that out, I fixed both issues! To be fair, TLC is technically MLC (MLC multi-level cell) NAND. Since TLC has 3-bits per cell it qualifies as MLC. It is sometimes referred to as 3-bit MLC. In the shows we’ve attended we have heard speakers refer to TLC as MLC as well due to this. It is just clearer to refer to TLC as TLC only.

Thanks for testing also the sequential write speed over the whole capacity 🙂

Sounds OK for 3D-TLC, but Samung Evo 500GB is almost 50% faster.

If the price go strong down the MX300 is maybe a good buy. But still waiting for other capacities

You’re welcome! We are patiently awaiting the other capacities as well. We are hoping to see improvements in the base write performance and when production ramps up, hopefully lower prices too! Right now $199.99 is the MSRP, so street costs should drop rather soon.

750 GB means there’s no direct competitor.
This should really be the replacement for the BX200 (which deserves LEMON status)
not the MX200-That would hopefully be replaced with 3D-MLC……………..
Be interesting to see what follows-Have a feeling speeds will tank on smaller drives-Be
interesting to see this size with a 8 ch controller……….

Yeah Sean there was obviously no forward thinking when Dual bit was named MLC…
Would be nice and simple if we had-SLC-DLC-TLC.

Still a happy C400 user……………………………………………..

Seems like a great all around drive. Has good performance, good feature set, and a good price. Can you name any other drives with similar performance or better performance that have power loss protection and encryption at this price point??

The Crucial MX300 OR the MyDigitalSSD BP5e?! What would you pick Sean? Will use it for sample libraries storing…dependent on speed and reliability and ofc power efficiency, don’t want any of my SSD’s to crack. Best regards!
