Crucial MX300 750GB SATA III SSD Review

TweakTown Rating: 87%Manufacturer: Crucial



Version and / or Patch Used: 2.47


ATTO is a timeless benchmark used to provide manufacturers with data used for marketing storage products.





Sequential read/write transfers max out at 536/513 MB/s. Both figures exceed Crucial's given maximum sequential performance. Maximum read performance is achieved at 1MB transfers, maximum write at 256KB transfers. Keep in mind this is our OS volume, and it is filled to 75% of its total capacity.


Sequential Write




The MX300 displays a nice performance curve with superior small file write performance up to 16KB transfers. Beyond 16KB transfers the MDD BP5e and TRION 150 lead the field.


Sequential Read




This is our first indication that the MX300 is more of a write centric SSD. Sequential read performance comes in at the bottom of our test pool. Crucial's own BX200 displays a better sequential read performance curve.



Anvil Storage Utilities


Version and / or Patch Used: 1.1.0


Anvil's Storage Utilities is a storage benchmark designed to measure the storage performance of SSDs. The Standard Storage Benchmark performs a series of tests; you can run a full test or just the read or write test, or you can run a single test, i.e. 4k QD16.








Anvil's scoring gives a good indication of a drive's overall performance. In terms of overall score, the MX300 outperforms the SP550, TRION 100 and the BX200 handily. A score of 4,913 gives us a good indication that the MX300 is a solid mid-level performer exactly as it is marketed by Crucial. If we focus in on write scoring we can see that the MX300 delivers the second best write score of the bunch.


(Anvil) Read IOPS through Queue Depth Scale




Because QD8 is still within consumer range, we feel the MX300 delivers overall the second best performance of the drive's in our test pool.


(Anvil) Write IOPS through Queue Scale




Great performance at QD1-2 is what we want to see and in this respect, the MX300 delivers the goods. At queue depths above two, the Phison S10 powered BP5e and TRION 150 lead the field.
