AS SSD Benchmark

Standard performance test

The standard test was performed with a 1 GB file. A total score of 735 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	446,56 MB/s	444,90 MB/s
4K in megabytes per second	45,33 MB/s	75,04 MB/s
4K-64Thrd in megabytes per second	185,06 MB/s	180,45 MB/s
Access time in milliseconds	0,041 ms	0,154 ms
Score	275	300
Total score	735

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 November 27, 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	984,32 MB/s	1,09 s
Program many small files	1242,74 MB/s	1,13 s
Game small and large files	1313,53 MB/s	1,05 s

Compression Performance Test

Here, the writing and reading speed of the the KIOXIA SATA SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 555MB/s and 540MB/s respectively).

CrystalDiskMark Benchmark

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