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 Windows Copy command (the cache remains enabled). The practical test of 12.08.2021 shows the performance for simultaneous write and read operations. The lower the duration, the better.

ATTO Disk Benchmark 4

Here a 256 MB file is written several times to the 128 GB PNY USB flash drive. The I/O block size varies (from 512 bytes to 64 megabytes). The larger the blocks, the faster they can usually be written and read.

HD Tune Pro 5.75 Benchmark

HD Tune writes a 1 GB file to the 128 GB PNY USB flash drive. The transfer data of the read speed is displayed graphically. The minimum, maximum and average values are also determined. The determined access time and burst rate are also displayed.
