AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 6642 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	3034,63 MB/s	2809,70 MB/s
4K in megabytes per second	55,92 MB/s	178,50 MB/s
4K-64Thrd in megabytes per second	2067,27 MB/s	2525,39 MB/s
Access time in milliseconds	0,025 ms	0,105 ms

Total score	6642

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 April 20, 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	1863,22 MB/s	1,23 s
Program many small files	763,59 MB/s	9,22 s
Game small and large files	1575,32 MB/s	4,39 s

Compression Performance Test

Here, the writing and reading speed of the the Samsung SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 3500MB/s and 3300MB/s respectively).

CrystalDiskMark Benchmark

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