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 23.12.2022 shows the performance for simultaneous write and read operations. The lower the duration, the better.

Compression Performance Test

Here, the write as well as read speed (according to the manufacturer 100 MB/s and 20 MB/s) the ADATA USB flash drive is measured depending on the compressibility of the data.

ATTO Disk Benchmark 4

Here a 256 MB file is written several times to the 64 GB ADATA 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 64 GB ADATA 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.

HD Tune Endurance test

A long-term test was performed here to fully utilize the memory. You can see when a cache is full and the write performance decreases.

SSD-Z 16 Benchmark

Similar to HD Tune, a 500 MB file is written to the 64 GB ADATA USB flash drive here. is written. The transfer data is displayed. The more constant the line, the better.
