AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 2830 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	1922,73 MB/s	1183,07 MB/s
4K in megabytes per second	64,45 MB/s	157,48 MB/s
4K-64Thrd in megabytes per second	774,68 MB/s	1011,45 MB/s
Access time in milliseconds	0,024 ms	0,144 ms
Score	1031	1287
Total score	2830

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 January 21, 2021 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	1322,27 MB/s	1,74 s
Program many small files	1089,85 MB/s	6,46 s
Game small and large files	1156,86 MB/s	5,97 s

Compression Performance Test

Here, the writing and reading speed of the the Kingston SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 2000MB/s and 1000MB/s respectively).

CrystalDiskMark Benchmark

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