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 September 23, 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	61,48 MB/s	17,47 s
Program many small files	39,55 MB/s	35,58 s
Game small and large files	54,79 MB/s	25,21 s

Compression Performance Test

Here, the writing and reading speed of the the Samsung USB flash driveSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 400MB/s and 60MB/s respectively).

CrystalDiskMark Benchmark

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