AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 3427 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	3218,22 MB/s	2527,57 MB/s
4K in megabytes per second	58,68 MB/s	156,28 MB/s
4K-64Thrd in megabytes per second	878,54 MB/s	1134,57 MB/s
Access time in milliseconds	0,023 ms	0,509 ms
Score	1259	1544
Total score	3427

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 January 24, 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	1825,43 MB/s	1,26 s
Program many small files	1213,64 MB/s	5,80 s
Game small and large files	1845,79 MB/s	3,74 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 3500MB/s and 2500MB/s respectively).

CrystalDiskMark Benchmark

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