AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 6779 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	4394,87 MB/s	3422,92 MB/s
4K in megabytes per second	64,53 MB/s	169,08 MB/s
4K-64Thrd in megabytes per second	2302,30 MB/s	2074,62 MB/s
Access time in milliseconds	0,023 ms	0,117 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 March 25, 2024 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	2344,70 MB/s	0,98 s
Program many small files	1128,82 MB/s	6,24 s
Game small and large files	1951,73 MB/s	3,54 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 5000MB/s and 4200MB/s respectively).

CrystalDiskMark Benchmark

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