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 19, 2020 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 SanDisk USB flash driveSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 150MB/s and 30MB/s respectively).
Here, two sequential and two random performance tests are performed, similar to the ones performed on the AS SSD.

HD Tune writes a 1 GB file to the 64 GB SanDisk USB flash drive. 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 64 GB SanDisk USB flash drive. The I/O block size varies (from 512 bytes to 64 megabytes). The larger the blocks, the faster they can be written and read.
