AS SSD Benchmark
Standard performance test
The standard test was performed using a 5 GB file. A total score of 1183 points was achieved.

Copy Performance Test
A common everyday situation is simulated here. Three test folders are created:
- ISO (folder with two large files)
- Program (folder with many small files)
- Game (folder with small and large files)
The three folders are copied using the Windows Copy command (the cache remains enabled). The practical test of January 05, 2024 shows the performance for simultaneous write and read operations. The lower the duration, the better the performance.

Compression Performance Test
This measures the write and read speed of the SSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 1050MB/s and 1050MB/s respectively).
CrystalDiskMark Benchmark
Here, two sequential and two random performance tests are performed, similar to the ones performed on the AS SSD.

HD Tune Pro Endurance test
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. 260 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 952 MB/s and written with 203 MB/s.
HD Tune Pro Benchmark
HD Tune writes a 5 GB file to the Lenovo external 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.
ATTO Disk Benchmark
Here, a 256 MB file is written several times to the Lenovo external SSD . The I/O block size varies (from 512 bytes to 64 megabytes). The larger the blocks, the faster they can be written and read.
SSD-Z Benchmark
Similar to HD Tune, a 500 MB file is written to the Lenovo external SSD here. is written. The transfer data is displayed. The more constant the line, the better.
