AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 9177 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	6095,53 MB/s	5680,20 MB/s
4K in megabytes per second	74,58 MB/s	201,39 MB/s
4K-64Thrd in megabytes per second	2829,85 MB/s	3120,51 MB/s
Access time in milliseconds	0,018 ms	0,094 ms
Score	3514	3890
Total score	9177

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 July 13, 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	2085,63 MB/s	1,10 s
Program many small files	1169,81 MB/s	6,02 s
Game small and large files	1950,52 MB/s	3,54 s

Compression Performance Test

Here, the writing and reading speed of the the SK hynix SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 7000MB/s and 6500MB/s respectively).

CrystalDiskMark Benchmark

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