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 October 14, 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	316,29 MB/s	3,40 s
Program many small files	118,03 MB/s	11,92 s
Game small and large files	236,31 MB/s	5,84 s

Compression Performance Test

Here, the writing and reading speed of the the Netac USB flash driveSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 550MB/s and 550MB/s respectively).

CrystalDiskMark Benchmark

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