AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 5052 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	4561,10 MB/s	4265,96 MB/s
4K in megabytes per second	61,26 MB/s	162,42 MB/s
4K-64Thrd in megabytes per second	1388,15 MB/s	1588,89 MB/s
Access time in milliseconds	0,024 ms	0,122 ms
Score	1906	2178
Total score	5052

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 August 05, 2024 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	2095,57 MB/s	1,10 s
Program many small files	1151,08 MB/s	6,12 s
Game small and large files	1938,34 MB/s	3,56 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 5200MB/s and 4700MB/s respectively).

CrystalDiskMark Benchmark

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