We put the Oreton SATA SSD through a detailed test. You can find the test result / test report here:


AS SSD Benchmark

Standard performance test

The standard test was performed with a 1 GB file. A total score of 596 points was achieved.

Copy performance test

A common everyday scenario 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 (cache remains enabled). The real-world test from 12 June 2026 shows performance during simultaneous write and read operations. The lower the duration, the better.

Compression performance test

Here, speed is measured depending on how compressible the data is.

CrystalDiskMark Benchmark

Similar to AS SSD, two sequential and two random performance tests are carried out here and the write and read speed (manufacturer specs: 550 MB/s and 520 MB/s) the Oreton SATA SSD is measured.

HD Tune Pro long-term test

A long-term test was performed to fully utilize the storage. You can see at what point the cache (if present) becomes full and write performance drops. A test file of 100 GB was written to the medium. After approx. 83 GB, the cache was full and performance was throttled.
The test file could at least be read with an average read speed of 468 MB/s and written at 178 MB/s.

ATTO Disk Benchmark

Here, a 256 MB file is written to the Oreton SATA SSD multiple times. The I/O block size varies (from 512 bytes to 64 megabytes). The larger the blocks, the faster writing and reading usually becomes.
