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 September 23, 2023 shows the performance for simultaneous write and read operations. The lower the duration, the better the performance.

Here, the writing and reading speed of the the SanDisk SATA SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 535MB/s and 445MB/s respectively).
Here, two sequential and two random performance tests are performed, similar to the ones performed on the AS SSD.
