AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 2124 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	2234,34 MB/s	1831,40 MB/s
4K in megabytes per second	45,28 MB/s	151,93 MB/s
4K-64Thrd in megabytes per second	792,80 MB/s	194,55 MB/s
Access time in milliseconds	0,028 ms	0,335 ms

Total score	2124

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 October 13, 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	1602,84 MB/s	1,43 s
Program many small files	623,59 MB/s	11,29 s
Game small and large files	379,35 MB/s	18,21 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 2400MB/s and 1650MB/s respectively).

CrystalDiskMark Benchmark

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