Crucial BX300 240GB SATA III SSD Review

TweakTown Rating: 97%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. With ATTO, we are looking at maximum sequential performance with compressible data as well as the performance curve.




Compressible sequential read/write transfers max out at 561/523 MB/s. Keep in mind this is our OS volume, and it is filled to 75% of its total capacity.


Sequential Write




A smooth performance curve and excellent small-file performance are what we are looking for and the BX300 delivers the goods.


Sequential Read




More of what we are looking for. Excellent small-file performance, smooth performance curve and high top-end speed.




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. With Anvil's, we are focused on the total score.








Anvil's scoring typically provides us with a good indication of a drive's overall synthetic performance. Whenever a SATA SSD scores 5,000 we take notice. Not many drives can do it, and this is the first time we've seen a Micron 3D flash equipped SATA drive hit our milestone mark. And, this is despite its capacity handicap at 240GB.


(Anvil) Read IOPS through Queue Depth Scale




With the drive filled to 75% of its total capacity, we fall short of the 84K random read IOPS listed on the factory spec. sheet.




The BX300 delivers respectable performance at QD1-QD2, but at higher queue depths, falls behind most of the drives in our test pool.


(Anvil) Write IOPS through Queue Scale




With the drive filled to 75% of its total capacity, we fall short of the 95K random write IOPS listed on the factory spec. sheet.




The BX300 absolutely owns the competing drives in our test pool when writing random data. The XPG SX950 is similarly configured (same controller and same flash) but can't hang with the BX300 despite its capacity advantage.
