AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 4188 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	4203,68 MB/s	2729,27 MB/s
4K in megabytes per second	59,92 MB/s	162,03 MB/s
4K-64Thrd in megabytes per second	830,09 MB/s	1831,46 MB/s
Access time in milliseconds	0,024 ms	0,125 ms

Total score	4188

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	2191,03 MB/s	1,05 s
Program many small files	1165,10 MB/s	6,04 s
Game small and large files	2069,83 MB/s	3,34 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 4800MB/s and 2900MB/s respectively).

CrystalDiskMark Benchmark

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