AS SSD Benchmark

Standard performance test

The standard test was performed with a 1 GB file. A total score of 1051 points was achieved.

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 July 22, 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	621,96 MB/s	1,73 s
Program many small files	226,36 MB/s	6,22 s
Game small and large files	461,86 MB/s	2,99 s

Compression Performance Test

Here, the writing and reading speed of the the Silicon Power USB flash driveSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 1050MB/s and 850MB/s respectively).

CrystalDiskMark Benchmark

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