AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 4508 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	3262,39 MB/s	3041,82 MB/s
4K in megabytes per second	58,60 MB/s	184,97 MB/s

Total score	4508

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 November 19, 2022 shows the performance for simultaneous write and read operations. The lower the duration, the better the performance.

AS SSD Copy-Benchmark	Transfer rate:	Duration:
ISO two large files	2024,29 MB/s	1,14 s
Program many small files	1212,21 MB/s	5,81 s
Game small and large files	1847,76 MB/s	3,74 s

Compression Performance Test

Here, the writing and reading speed of the the Western Digital SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 3500MB/s and 3500MB/s respectively).

CrystalDiskMark Benchmark

Here, two sequential and two random performance tests are performed, similar to the ones performed on the AS SSD.
