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 June 18, 2021 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 the Sabrent SSD, depending on the compressibility of the data (according to the manufacturer, these should be 7000 MB/s and 5300 MB/s respectively).

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.

HD Tune Endurance Test TEST: Sabrent Rocket 4 Plus 1TB

HD Tune Pro Benchmark

HD Tune writes a 5 GB file to the Sabrent 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.

ATTO Disk Benchmark

Here, a 256 MB file is written several times to the Sabrent 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.

SSD-Z Benchmark

Similar to HD Tune, a 500 MB file is written to the Sabrent M.2 SSD here. The transfer data is displayed. The more constant the line, the better. Unfortunately, the tool does not work correctly above about 5,000 MB/s and no line (and sometimes wrong min and max data) is displayed.
