AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 1343 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	1867,46 MB/s	1890,16 MB/s
4K in megabytes per second	24,51 MB/s	70,71 MB/s
4K-64Thrd in megabytes per second	410,05 MB/s	138,09 MB/s
Access time in milliseconds	0,055 ms	0,344 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 November 23, 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	119,65 MB/s	19,21 s
Program many small files	146,88 MB/s	47,92 s
Game small and large files	379,43 MB/s	18,21 s

Compression Performance Test

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

CrystalDiskMark Benchmark

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