AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 2434 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	1983,78 MB/s	1605,44 MB/s
4K in megabytes per second	43,01 MB/s	165,70 MB/s
4K-64Thrd in megabytes per second	697,82 MB/s	696,31 MB/s
Access time in milliseconds	0,022 ms	0,624 ms
Score	939	1023
Total score	2434

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 17, 2023 shows the performance for simultaneous write and read operations. The lower the duration, the better the performance.

AS SSD Copy-Benchmark	Transfer rate:	Duration:
ISO two large files	1839,07 MB/s	1,25 s
Program many small files	1117,12 MB/s	6,30 s
Game small and large files	1714,92 MB/s	4,03 s

Compression Performance Test

Here, the writing and reading speed of the the fanxiang SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 2150MB/s and 1600MB/s respectively).

CrystalDiskMark Benchmark

Here, two sequential and two random performance tests are performed, similar to the ones performed on the AS SSD.
