A common everyday situation is simulated here. Three test folders are created:
The three folders are copied using the Windows Copy command (the cache remains enabled). The practical test of December 10, 2022 shows the performance for simultaneous write and read operations. The lower the duration, the better the performance.

This measures the write and read speed of the the Lexar SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 7500MB/s and 6300MB/s respectively).
Here, two sequential and two random performance tests are performed, similar to the ones performed on the AS SSD.

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.
HD Tune writes a 5 GB file to the Lexar M.2 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.
Here, a 256 MB file is written several times to the Lexar M.2 SSD. The I/O block size varies (from 512 bytes to 64 megabytes). The larger the blocks, the faster they can be written and read.
Similar to HD Tune, a 500 MB file is written to the Lexar M.2 SSD here. The transfer data is displayed. The more constant the line, the better. Unfortunately the tool does not work correctly above about 5,000 MB/s and no line (and sometimes wrong min and max data) is displayed.
