Copy Performance Test
A common everyday situation 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 (the cache remains enabled). The practical test of September 16, 2025 shows the performance for simultaneous write and read operations. The lower the duration, the better the performance.

Compression Performance Test
Here, the writing and reading speed of the the Gigabyte SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 4000MB/s and 3900MB/s respectively).
CrystalDiskMark Benchmark
Here, two sequential and two random performance tests are performed, similar to the ones performed on the AS SSD.

HD Tune Pro Endurance test
A long-term test was performed here to make full use of the memory capacity. You can see when a cache is full and the writing performance decreases.
A test file of 100 GB was written to the medium.
After approx. 50 GB, the pSLC-Cache was full and the performance was throttled.
The average read speed was 3640 MB/s and the average write speed was 1922 MB/s.
ATTO Disk Benchmark
Here, a 256 MB file is written several times to the Gigabyte M.2 SSD . The I/O block size varies (from 512 bytes to 64 megabytes). The larger the blocks, the faster they can be written and read.
SSD-Z Benchmark
Similar to HD Tune, a 500 MB file is written to the Gigabyte M.2 SSD here. is written. The transfer data is displayed. The more constant the line, the better.
