Copy performance test

A common everyday scenario 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 (cache remains enabled). The real-world test from 12 October 2023 shows performance during simultaneous write and read operations. The lower the duration, the better.

Compression performance test

Here, speed is measured depending on how compressible the data is.

CrystalDiskMark Benchmark

Similar to AS SSD, two sequential and two random performance tests are carried out here and the write and read speed (manufacturer specs: 150 MB/s and 100 MB/s) the SSK USB flash drive is measured.

HD Tune Pro long-term test

A long-term test was performed to fully utilize the storage. You can see at what point the cache (if present) becomes full and write performance drops. A test file of 4 GB was written to the medium.

ATTO Disk Benchmark

Here, a 256 MB file is written to the 128 GB SSK USB flash drive multiple times. The I/O block size varies (from 512 bytes to 64 megabytes). The larger the blocks, the faster writing and reading usually becomes.

SSD-Z Benchmark

Similar to HD Tune, a 500 MB file is written to the 128 GB SSK USB flash drive here. The transfer data is displayed. The more consistent the line, the better. Unfortunately, the tool no longer works correctly from around 4,000 MB/s and no line is displayed (and sometimes incorrect min/max data is shown).
