AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 3430 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	3851,39 MB/s	1843,79 MB/s
4K in megabytes per second	55,78 MB/s	185,60 MB/s

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 26, 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	1529,36 MB/s	1,50 s
Program many small files	1208,05 MB/s	5,83 s
Game small and large files	1799,29 MB/s	3,84 s

Compression Performance Test

Here, the writing and reading speed of the the Crucial SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 4700MB/s and 1900MB/s respectively).

CrystalDiskMark Benchmark

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