When it comes to sequential read performance the Samsung SSD 850 Evo was as good as any SATA SSD that we have tested. Achieving a throughput of 521MB/s meant that the 850 Evo was able to deliver similar performance to the SanDisk Extreme Pro.
The sequential write performance was also very strong and again the Samsung SSD 850 Evo matched the SanDisk Extreme Pro.
When it came to random 512K performance the Samsung SSD 850 Evo was only a fraction faster than the previous 840 Evo model. That said with a throughput of 427MB/s it was just 10MB/s slower than the Crucial MX100.
The random 512K write performance of the Samsung SSD 850 Evo was virtually identical to that of the previous model which is a shame as the performance is below average here.
The random 4K-QD32 performance of the Samsung SSD 850 Evo has been massively improved over the previous model, when measuring read performance an extra 41% throughput was achieved. This also meant that the 850 Evo was 21% faster than the Crucial MX100.
Here we see that the random 4K-QD32 write performance has also been improved substantially going from 199MB/s on the 840 Evo to a more impressive 342MB/s, a 72% increase.
