Crucial MX300 SSD Review (1050GB) – Micron 3D NAND Meets RAID 0


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.

Crystal Disk Mark also shows that the 1050GB MX300 delivers very good mainstream performance. Nearly 1GB/s read and write were reached in RAID 0. 4K numbers are good in both single drive and RAID 0 configurations. On an interesting note, 4K QD 32 speeds didn’t increase much when utilizing one worker, therefore to get the most out of the RAID 0 config, the software needs to utilize multiple threads, not just one.


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 1050GB Crucial MX300 attained an overall score of 1150 points and 1729 in RAID 0. Overall, the speeds are very similar to that of the 750GB model. In RAID 0 the sequential speeds reached 935MB/s read and 944MB/s write. QD1 4K read speed decreased slightly, but write speed doubled. Furthermore, we were able to reach 128K IOPS read and 111K IOPS write when in RAID 0. During the copy test the speed nearly doubled in all benchmarks. A best of 818MB/s was achieved during the ISO portion.


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, AS SSD mirrors over the results we have seen in our other benchmarks. Sequential speeds double in RAID 0, 4K write doubles while read does not, but overall, we see a nice improvement in performance.

    1TB prices still too high

    Thanks for the review with the HD Tune 🙂

    It´s essiential for me to see how fast a SSD is if the SLC-cache is full

    I wonder if Crucial SE still can’t update SSD firmware if boot drive is an NVMe device. I reported this problem ages ago, curious if they fixed this annoyance.

    Performance-wise. I would still pick 850EVO. If anyone wants blazing speed for data then get any supported SSD, activate RAPID mode (careful, not advisable on boot drive) and enjoy. I have one activated on 1TB model with R/W at 7500MB/s and NVMe is nowhere (owning couple of i750s).

    Would you benchmark also the smallest model? I can’t find any benchmarks of MX300 275GB on the net, and I’m curious how much performance it sacrifices due to reduced die count.

    Shorely this is not the scent of some Kibutzim Kowboy on Da Yeehaw? You know, where the ability to Fool The Fool-ables is not as Easy as any PC.

    That which is true, is true for ALL. Unlike “Les Da Tokar”, we all have 2 Eyes, 2 Ears, etc.. So Guyz N Galz, “review” like with like or else comparing Apples to Oranges is meaningless to either Apples or Oranges when comparing. Unless, Da Stupide-Dumbe are all-a-congregating over here at Da SSD Review Festivaal. Next, “they” be saying that Pillaging & Plundering is AOK beecuz some Booke sez, “Eets OK, Munn !”

    C’mon, shorely The Stupid-Dumb are dying-off as quickly as Pillaging & Plundering are flourishing beecuz Da Kibuttzim Kowboys are now nuclear-tipped armed. Why do it, even when you can? Unless ……. like “Les”, yore Eyes are like Da Cyclops.

    FYI I picked up 2x 750GB on sale and run in Raid 0. 33% more capacity than the 1TB version for the same price and WAY faster in Raid 0 than 1x1TB, I am pretty pleased, keep an eye out for that option.
