We put the fanxiang NVMe M.2 SSD through a detailed test. You can find the test result / test report here:
The standard test was performed with a 5 GB file. A total score of 5052 points was achieved.
A common everyday scenario is simulated here. Three test folders are created:
The three folders are copied using the Windows copy command (cache remains enabled). The real-world test from 05 August 2024 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 |
2,095.57 MB/s |
1.10 s |
| Program typical program folder with many small files |
1,151.08 MB/s |
6.12 s |
| Game a game folder with small and large files |
1,938.34 MB/s |
3.56 s |
Here, speed is measured depending on how compressible the data is.
Similar to AS SSD, two sequential and two random performance tests are carried out here and the write and read speed (manufacturer: 5200 MB/s and 4700 MB/s) the fanxiang SSD is determined.

A long-term test was performed to fully utilize the storage. You can see from when a possible cache is full and write performance drops. A test file of 300 GB was written to the medium. The exact cache size could not be determined because the test file did not exhaust (push to the limit) the cache. The test file could at least be read with an average read speed of 3,637 MB/s and written at 4,181 MB/s.
HD Tune writes a 5 GB file to the fanxiang 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.

Here, a 256 MB file is written to the fanxiang 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.

Similar to HD Tune, a 500 MB file is written to the fanxiang 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).
