ADATA XPG Gammix S10 M.2 NVMe SSD Review (512GB)


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.

In ATTO the ADATA XPG Gammix S10 delivers speeds of up to 1.76GB/s read and 863MB/s write.


Crystal Disk Benchmark is used to measure read and write performance through a 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.

The ADATA XPG Gammix S10’s results in Crystal Disk Mark are similar with a sequential read result of 1829MB/s and sequential write result of 860MB/s. 4K QD1 random read/write speeds are decent with results of 37MB/s and 196MB/s, respectively.


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.

In AS SSD, the Gammix S10 achieved an overall score of 1902 points. Sequential read speed comes in at 1,546MB/s and sequential write speed comes in at 858MB/s. Here it also delivered 124K/170K IOPS read/write. Additionally, 4K QD1 results are similar to what we see with SATA SSDs, with 34MB/s read and 153MB/s write.

During the copy tests, it delivered nearly 1.2GB/s for the ISO portion, 460MB/s for the Program portion, and 900MB/s for the Game portion.


Anvil’s Storage Utilities (ASU) is 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 once again confirms all the performance numbers we have been seeing and overall the ADATA XPG Gammix S10 scored 8,023 points.

  1. Mr. Webster, thanks for the review as usual.
    Man oh man, these are some rough benchmarks. A solid notch above the worst drive. In the 30GB transfer test it abysmally gives way to 850 EVO? I certainly agree with you, there is no way this is a device for “professionals”.
