AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 3318 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	3137,04 MB/s	3312,50 MB/s
4K in megabytes per second	44,53 MB/s	74,04 MB/s
4K-64Thrd in megabytes per second	845,29 MB/s	1076,55 MB/s
Access time in milliseconds	0,039 ms	0,191 ms
Score	1204	1482
Total score	3318

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 September 02, 2024 shows the performance for simultaneous write and read operations. The lower the duration, the better the performance.

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 3800MB/s and 3700MB/s respectively).

CrystalDiskMark Benchmark

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