4. AS SSD benchmark
We move on with the AS SSD benchmark, which contains five synthetic as well as three practical tests. The synthetic tests determine the sequential and the random read / write performance of an SSD. These tests are carried out without using the operating system's cache. The Seq-test measures how long it takes to read and write an 1GB file. Most importantly, this sequential benchmark uses incompressible data for all of its transfers.
The AS SSD Benchmark with the 970 PRo SSD completed with an overall score of 4,994 points.
Sequential speeds for the drive hit the 2925 MB/s for reads and 2190 MB/s write. The drive's 4K random speeds reached the 59.7 MB/s for read and 174 MB/s for write. The drive's 64-thread 4K random read and write performance was impressive:
The AS SSD Copy-Benchmark showed impressive results ranging from 1656.91 MB/s in the program workload and up to 2162 MB/s in the ISO test:
Next up we ran the Compression Benchmark built-into AS SSD. This test uses a mix of compressible and incompressible data and outputs both Read and Write throughput of the drive.
The Samsung 970 PRO 512GB SSD showed a relatively stable behavior across the board, with some brief dips in the graphs:
