AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 6506 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	2986,88 MB/s	3072,00 MB/s
4K in megabytes per second	53,18 MB/s	174,06 MB/s
4K-64Thrd in megabytes per second	1633,61 MB/s	3016,09 MB/s
Access time in milliseconds	0,027 ms	0,127 ms
Score	1985	3497
Total score	6506

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 November 22, 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	1943,47 MB/s	1,18 s
Program many small files	1213,71 MB/s	5,80 s
Game small and large files	1853,01 MB/s	3,73 s

Compression Performance Test

Here, the writing and reading speed of the the KIOXIA SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 3400MB/s and 3200MB/s respectively).

CrystalDiskMark Benchmark

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