AS SSD Benchmark

Standard performance test

The standard test was performed with a 1 GB file. A total score of 699 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	494,20 MB/s	448,51 MB/s
4K in megabytes per second	29,20 MB/s	88,47 MB/s
4K-64Thrd in megabytes per second	181,17 MB/s	163,65 MB/s
Access time in milliseconds	0,047 ms	0,127 ms
Score	260	297
Total score	699

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 07, 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	1038,53 MB/s	1,03 s
Program many small files	1098,74 MB/s	1,28 s
Game small and large files	1484,09 MB/s	0,93 s

Compression Performance Test

Here, the writing and reading speed of the the fanxiang SATA SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 550MB/s and 500MB/s respectively).

CrystalDiskMark Benchmark

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