AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 3984 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	2957,23 MB/s	1973,56 MB/s
4K in megabytes per second	54,51 MB/s	180,01 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 February 17, 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	1731,57 MB/s	1,33 s
Program many small files	748,69 MB/s	9,40 s
Game small and large files	1457,48 MB/s	4,74 s

Compression Performance Test

Here, the writing and reading speed of the the Corsair SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 3480MB/s and 1880MB/s respectively).

CrystalDiskMark Benchmark

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