Version and / or Patch Used: 2.47


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




Write transfers ramp up quicker than read transfers. Read/write parity is achieved at 64kB transfers. Read transfers max out at 1.086 GB/s, while write transfers max out at 0.9683 GB/s.


Sequential Write




Write performance is second only to our EVO array.


Sequential Read




Sequential read transfers ramp up slower than the rest of the arrays on our chart.



Anvil Storage Utilities


Version and / or Patch Used: RC6


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.




Approaching 10,000 points, our 2-drive array is delivering awesome performance, especially with writing data.


Read IOPS through Queue Depth Scale




Read performance is lower than most of the arrays on our chart.


Write IOPS through Queue Scale




Our M550 array is pumping out exceptional write performance.





Version and / or Patch Used: 3.0 Technical Preview


CrystalDiskMark is disk benchmark software that allows us to benchmark 4k and 4k queue depths with accuracy.


Note: Crystal Disk Mark 3.0 Technical Preview was used for these tests since it offers the ability to measure native command queuing at 4 and 32.




Sequential read performance and random 4k write performance is outstanding.




512k read performance stands out in comparison to the other arrays on our chart.




4k random write performance is considered one of the most important performance metrics, and our M550 array delivers the goods.





Version and / or Patch Used: 1.7.4739.38088


AS SSD determines the performance of Solid-State Drives (SSD). The tool contains four synthetic as well as three practice tests. The synthetic tests are to determine the sequential and random read and write performance of the SSD.






With the last of our synthetic testing completed, let's move to our light usage model testing that will give us a better idea of what's under the hood of our M550 array.
