AS SSD Benchmark

Standard performance test

The standard test was performed with a 1 GB file. A total score of 281 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	507,45 MB/s	343,11 MB/s
4K in megabytes per second	14,93 MB/s	37,93 MB/s
4K-64Thrd in megabytes per second	60,76 MB/s	19,95 MB/s
Access time in milliseconds	3,625 ms	1,413 ms

Total score	281

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 August 24, 2023 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	832,80 MB/s	1,29 s
Program many small files	1108,17 MB/s	1,27 s
Game small and large files	1444,04 MB/s	0,96 s

Compression Performance Test

Here, the writing and reading speed of the the Western Digital SATA SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 545MB/s and 0MB/s respectively).

CrystalDiskMark Benchmark

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