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.




Sequential Write




Both capacities deliver sequential write performance that is at or above factory spec. The 2TB model delivers better performance than the 1TB model. Both capacities display an excellent performance curve on the low-end where it matters most.


Sequential Read




Both capacity points achieve their rated sequential performance. The performance curve of both capacities is similar. The MX300 is a write-centric SSD as we can clearly see from the results of this test. The majority of the competing SSDs in our test pool outperform the MX300 when reading sequential data.




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. When evaluating TLC-based SSDs, we are looking for a minimum score of 4,500. Both capacity points give us what we are looking for; and then some.


(Anvil) Read IOPS through Queue Depth Scale




We are hitting factory spec at QD32 even when the drives are 75% full.




The MX300 runs at the low-end of the test pool when reading data at lower queue depths. This is as expected for a write-centric SSD. At higher queue depths, the MX300 comes on strong.


(Anvil) Write IOPS through Queue Scale




We are hitting factory spec at QD32 even when the drives are 75% full.




Low queue depth performance is what we are looking for, and this is where we find the MX300 delivering excellent performance. In fact, at QD2 the MX300 at both capacity points is leading all contenders in our test pool.
