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 January 19, 2021 shows the performance for simultaneous write and read operations. The lower the duration, the better the performance.
