A common everyday situation is simulated here. Three test folders are created:
The three folders are copied using Windows Copy command (the cache remains enabled). The practical test of 10.12.2022 shows the performance for simultaneous write and read operations. The lower the duration, the better.

Here, the write as well as read speed (according to the manufacturer 7500 MB/s and 6300 MB/s) the Lexar SSD is measured depending on the compressibility of the data.
Similar to AS SSD, two sequential and two random performance tests are performed.

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 usually be written and read.
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.
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.
Similar to HD Tune, a 500 MB file is written to the Lexar M.2 SSD here. is written. The transfer data is displayed. The more constant the line, the better. Unfortunately the tool does not work correctly from about 5,000 MB/s and no line (and partly wrong min and max data) is displayed.
