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.




The 850 EVO's sequential read/write transfers max out at 546/523 MB/s, the 850 PRO 543/521 MB/s. Keep in mind these are both OS volumes 75% full, and we are properly converting KB to MB.


Sequential Write




We are charting a 500GB 850 EVO and a 512GB 850 PRO throughout the review to compare against the 2TB version's that are the focus of today's review. The performance of the Samsung drives are very similar and because of that, graphing lines may be layered one over the other on some of our charts.


Sequential Read




As we would expect to see, the Samsung drives all follow the same 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 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. The 850 Series drives all outperform the competition by a large margin in this test. The 2TB 850 PRO sets a new lab record for SATA SSD's.


(Anvil) Read IOPS through Queue Depth Scale




The smaller capacity 850 Series drives are able to slightly outperform the 2TB versions when reading random data.


(Anvil) Write IOPS through Queue Scale




The 500GB M.2 850 EVO is the winner at QD1-2 after that, Kingston's HyperX Savage takes command.
