AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 4445 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	3466,66 MB/s	3653,47 MB/s
4K in megabytes per second	68,57 MB/s	196,68 MB/s
4K-64Thrd in megabytes per second	965,15 MB/s	1768,88 MB/s
Access time in milliseconds	0,018 ms	0,118 ms

Total score	4445

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 December 14, 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	2247,41 MB/s	1,02 s
Program many small files	1157,42 MB/s	6,08 s
Game small and large files	1937,22 MB/s	3,57 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 4150MB/s and 4000MB/s respectively).

CrystalDiskMark Benchmark

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