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 November 30, 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 Transcend USB flash driveSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 400MB/s and 420MB/s respectively).
Here, two sequential and two random performance tests are performed, similar to the ones performed on the AS SSD.
