AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 2973 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	1605,24 MB/s	1191,97 MB/s
4K in megabytes per second	50,37 MB/s	163,37 MB/s
4K-64Thrd in megabytes per second	766,76 MB/s	1219,74 MB/s
Access time in milliseconds	0,026 ms	0,124 ms
Score	978	1502
Total score	2973

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 April 08, 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	1401,18 MB/s	1,64 s
Program many small files	1076,48 MB/s	6,54 s
Game small and large files	1185,11 MB/s	5,83 s

Compression Performance Test

Here, the writing and reading speed of the the KIOXIA SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 1700MB/s and 1200MB/s respectively).

CrystalDiskMark Benchmark

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