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 July 11, 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 Crucial SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 13600MB/s and 10200MB/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 400 GB was written to the medium.
After approx. 340 GB, the pSLC-Cache was full and the performance was throttled.
At least the test file could be read with an average write speed of 10376 MB/s and written with 3975 MB/s.
ATTO Disk Benchmark
Here, a 256 MB file is written several times to the Crucial 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 Crucial M.2 SSD here. is written. The transfer data is displayed. The more constant the line, the better. Unfortunately the tool does not work correctly from about 5,000 MB/s and no line (and partly wrong min and max data) is displayed.
