Corsair Neutron NX500 NVMe SSD Review (400GB)


ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

Initial results with ATTO are similar to that of the MP500, however, write performance is slightly lower. For reads, we got the rated 3GB/s, but for writes, it reached just 2.31GB/s.


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.

Utilizing Crystal Disk Mark now, the Corsair NX500 displays, again, similar results to that of the MP500 and easily achieves its rated spec of 2.8GB/s read and is just shy of 1.6GB/s write. 4K performance comes in at 48MB/s for read and 155MB/s for write.


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.

Looking at AS SSD we can see that the NX500 achieved an overall score of 2701. Sequential performance is better than that of the MP500 here, but overall, it is slightly lower. During the Copy Benchmark, the NX500 beat out the MP500 in the ISO and Game categories.


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.

Anvil Storage Utilities again illustrates similar performance results as those shown previously. Overall it achieved an overall score of 10,326.
