AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 1887 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	2253,29 MB/s	1208,58 MB/s
4K in megabytes per second	48,66 MB/s	133,66 MB/s
4K-64Thrd in megabytes per second	384,06 MB/s	673,05 MB/s
Access time in milliseconds	0,035 ms	0,251 ms

Total score	1887

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 April 19, 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	1435,15 MB/s	1,60 s
Program many small files	1004,13 MB/s	7,01 s
Game small and large files	1182,17 MB/s	5,84 s

Compression Performance Test

Here, the writing and reading speed of the the ADATA SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 2100MB/s and 100MB/s respectively).

CrystalDiskMark Benchmark

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