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 24, 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 KIOXIA SSD, depending on the compressibility of the data (according to the manufacturer, these should be 5000 MB/s and 3900 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.
After approx. 225 GB, the pSLC-Cache was full and the performance was throttled.
At least the test file could be read with an average write speed of 3372 MB/s and written with 1614 MB/s.
HD Tune writes a 5 GB file to the KIOXIA 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 KIOXIA 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 KIOXIA M.2 SSD here. The transfer data is displayed. The more constant the line, the better.
