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 July 22, 2024 shows the performance for simultaneous write and read operations. The lower the duration, the better the performance.

Compression Performance Test

This measures the write and read speed of the the Silicon Power USB flash driveSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 1050MB/s and 850MB/s respectively).

HD Tune Pro Endurance test

This is a long term test to make full use of the memory capacity. You can see when a cache is full and the writing performance decreases. A test file of 100 GB was written to the medium. After approx. 24 GB, the pSLC-Cache was full and the performance was throttled.
At least the test file could be read with an average write speed of 317 MB/s and written with 346 MB/s.

HD Tune Pro Benchmark

HD Tune writes a 1 GB file to the 250 GB Silicon Power 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.

ATTO Disk Benchmark

Here, a 256 MB file is written several times to the 250 GB Silicon Power USB flash drive. The I/O block size varies (from 512 bytes to 64 megabytes). The larger the blocks, the faster they can be written and read.

SSD-Z Benchmark

Similar to HD Tune, a 500 MB file is written to the 250 GB Silicon Power USB flash drive here. The transfer data is displayed. The more constant the line, the better.
