AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 3156 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	2694,86 MB/s	1967,38 MB/s
4K in megabytes per second	58,09 MB/s	181,13 MB/s
4K-64Thrd in megabytes per second	265,30 MB/s	1896,27 MB/s
Access time in milliseconds	0,022 ms	0,105 ms

Total score	3156

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 30, 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	1783,56 MB/s	1,29 s
Program many small files	1136,83 MB/s	6,19 s
Game small and large files	1894,86 MB/s	3,65 s

Compression Performance Test

Here, the writing and reading speed of the the Emtec SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 5000MB/s and 4400MB/s respectively).

CrystalDiskMark Benchmark

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