TweakTown Rating: 98%Manufacturer: Samsung



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 transfers max out at 540 MB/s. Sequential write transfers max out at 516 MB/s. We are able to hit and exceed sequential specifications even at 75% full.


Sequential Write




Our 850 EVO M.2 has the third highest sequential write speed of the drives on our chart.


Sequential Read




Reading sequential data, the 850 EVO M.2 again finishes in about third place.



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 SSD's. 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 drives overall performance. Second only to the 850 Pro, the EVO is starting to flex some muscle.


(Anvil) Read IOPS through Queue Depth Scale




The 850 EVO M.2 delivers incredible random read performance. We are able to exceed Samsung's specification of 97,000 IOPS. The 850 EVO begins separating itself from the pack at QD4, and again finishes second only to the 850 Pro.


(Anvil) Write IOPS through Queue Scale




The vast majority of random writes occur at QD1-QD2 and that's exactly where the 850 EVO M.2 leaves the competition in the dust.
