AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 959 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	750,88 MB/s	762,44 MB/s
4K in megabytes per second	21,08 MB/s	88,97 MB/s
4K-64Thrd in megabytes per second	169,57 MB/s	383,80 MB/s
Access time in milliseconds	0,116 ms	0,215 ms

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 November 11, 2022 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	714,98 MB/s	3,21 s
Program many small files	154,73 MB/s	45,49 s
Game small and large files	363,80 MB/s	18,99 s

Compression Performance Test

Here, the writing and reading speed of the SSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 800MB/s and 800MB/s respectively).

CrystalDiskMark Benchmark

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