AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 2752 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	2718,08 MB/s	1238,24 MB/s
4K in megabytes per second	61,25 MB/s	153,78 MB/s
4K-64Thrd in megabytes per second	774,62 MB/s	856,11 MB/s
Access time in milliseconds	0,033 ms	0,731 ms

Total score	2752

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 03, 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	1563,98 MB/s	1,47 s
Program many small files	1068,10 MB/s	6,59 s
Game small and large files	1188,68 MB/s	5,81 s

Compression Performance Test

Here, the writing and reading speed of the the Mushkin SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 3100MB/s and 1400MB/s respectively).

CrystalDiskMark Benchmark

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