AS SSD Benchmark

Standard performance test

The standard test was performed with a 1 GB file. A total score of 37 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	109,53 MB/s	27,90 MB/s
4K in megabytes per second	5,97 MB/s	0,94 MB/s
4K-64Thrd in megabytes per second	5,45 MB/s	0,95 MB/s
Access time in milliseconds	0,365 ms	2,758 ms

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 February 13, 2024 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	26,68 MB/s	40,25 s
Program many small files	13,00 MB/s	108,22 s
Game small and large files	21,62 MB/s	63,87 s

Compression Performance Test

Here, the writing and reading speed of the the ADATA USB flash driveSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 100MB/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.
