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 30, 2023 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	578,85 MB/s	1,86 s
Program many small files	214,70 MB/s	6,55 s
Game small and large files	444,40 MB/s	3,11 s

Compression Performance Test

Here, the writing and reading speed of the the Transcend USB flash driveSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 1050MB/s and 900MB/s respectively).

CrystalDiskMark Benchmark

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