We put the Gigabyte NVMe M.2 SSD through a detailed test. You can find the test result / test report here:
AS SSD Benchmark
Standard performance test
The standard test was performed with a 5 GB file. A total score of 2275 points was achieved.
Copy performance test
A common everyday scenario is simulated here. Three test folders are created:
- ISO (folder with two large files)
- Program (folder with many small files)
- Game (folder with small and large files)
The three folders are copied using the Windows copy command (cache remains enabled). The real-world test from 27 March 2025 shows performance during simultaneous write and read operations. The lower the duration, the better.
| AS SSD Copy Benchmark | Transfer rate: | Duration: |
|---|---|---|
| ISO two large files |
1,790.36 MB/s |
1.28 s |
| Program typical program folder with many small files |
1,100.76 MB/s |
6.39 s |
| Game a game folder with small and large files |
1,755.42 MB/s |
3.94 s |
Compression performance test
Here, speed is measured depending on how compressible the data is.
CrystalDiskMark Benchmark
Similar to AS SSD, two sequential and two random performance tests are carried out here and the write and read speed (manufacturer specs: 2400 MB/s and 1800 MB/s) the Gigabyte SSD is measured.

HD Tune Pro long-term test
A long-term test was performed to fully utilize the storage. You can see at what point the cache (if present) becomes full and write performance drops. A test file of 300 GB was written to the medium. After approx. 250 GB, the cache was full and performance was throttled.
The test file could at least be read with an average read speed of 1,477 MB/s and written at 372 MB/s.
HD Tune Pro Benchmark
HD Tune writes a 5 GB file to the Gigabyte NVMe M.2 SSD. The transfer data of the read speed is displayed graphically. The minimum, maximum and average values are also determined. The measured access time and burst rate are also shown.
ATTO Disk Benchmark
Here, a 256 MB file is written to the Gigabyte NVMe M.2 SSD multiple times. The I/O block size varies (from 512 bytes to 64 megabytes). The larger the blocks, the faster writing and reading usually becomes.
SSD-Z Benchmark
Similar to HD Tune, a 500 MB file is written to the Gigabyte NVMe M.2 SSD here. The transfer data is displayed. The more consistent the line, the better. Unfortunately, the tool no longer works correctly from around 4,000 MB/s and no line is displayed (and sometimes incorrect min/max data is shown).
