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.

Scoring

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.
