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 January 03, 2024 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 Samsung SSD, depending on the compressibility of the data (according to the manufacturer, these should be 3500 MB/s and 2300 MB/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. A test file of 300 GB was written to the medium. The exact cache size could not be determined, because the test file did not exhaust the cache (brought it to the limit). At least the test file could be read with an average write speed of 3257 MB/s and written with 2213 MB/s.
HD Tune writes a 5 GB file to the Samsung 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 Samsung M.2 SSD. The I/O block size varies (from 512 bytes to 64 megabytes). The larger the blocks, the faster they were written and read.
Similar to HD Tune, a 500 MB file is written to the Samsung M.2 SSD here. The transfer data is displayed. The more constant the line, the better.
