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 20, 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 external SSD from Lexar, depending on the compressibility of the data (according to the manufacturer, these should be 2000 MB/s and 1800 MB/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 300 GB was written to the medium. After approx. 38 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 1951 MB/s and written with 1435 MB/s.

HD Tune Pro Benchmark

HD Tune writes a 5 GB file to the Lexar external SSD. 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 Lexar external SSD. The I/O block size varies (from 512 bytes to 64 megabytes). The larger the blocks, the faster they were written and read.

SSD-Z Benchmark

Similar to HD Tune, a 500 MB file is written to the Lexar external SSD here. The transfer data is displayed. The more constant the line, the better.
