Samsung 850 EVO SSD Review (4TB) – Bigger than Ever!!!

CRYSTAL DISK BENCHMARK VER. 4.0.3 X64

Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.

In Crystal Disk Mark the 4TB Samsung 850 EVO reached over 555MB/s read and 534MB/s write. 4K reads and writes are very good as well, reaching over 40MB/s read and nearly 160MB/s write. These results are indicative of very good performance so far.

AS SSD BENCHMARK VER 1.8

The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance. For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.

When testing in AS SSD the 850 EVO reached an overall score of 1239 points. Sequential speeds are a bit less than the other benches, reaching just 521MB/s read and 501MB/s write. 4K read and write higher than crystal disk mark, on the other hand, reaching an 45MB/s read and 132MB/s write. Furthermore, it reaches 95K IOPS read and 83K IOPS write, a bit below the manufacturer’s rating, but still very good.

This AS SSD Copy Bench test is a true to life evaluation of performance as AS SSD creates three files (ISO/Program/Game), and simply moves them from one part of the SSD to another, recording their top speed and total transfer time. The best speed of 462MB/s was achieved via the Game test, however, even the rest of the results are very good.

ANVIL STORAGE UTILITIES PROFESSIONAL

Anvil’s Storage Utilities (ASU) are the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.

In Anvil Storage Utilities the 4TB Samsung 850 EVO scored 5,535 points. Max sequential read speeds reach 520MB/s and sequential write comes in at 500MB/s. 4K speeds prove similar to the other benchmarks, 38MB/s for read and 142MB/s for write.
