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 08.04.2021 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 200 MB/s and 60 MB/s) the Kingston USB flash drive 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 128 GB Kingston USB flash drive. 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 1 GB file to the 128 GB Kingston 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.
Similar to HD Tune, a 500 MB file is written to the 128 GB Kingston USB flash drive here. is written. The transfer data is displayed. The more constant the line, the better.
