AS SSD Benchmark

Standard performance test

The standard test was performed with a 1 GB file. A total score of 397 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	506,54 MB/s	406,39 MB/s
4K in megabytes per second	17,20 MB/s	37,84 MB/s
4K-64Thrd in megabytes per second	89,63 MB/s	78,50 MB/s
Access time in milliseconds	1,183 ms	0,767 ms
Score	157	157
Total score	397

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 22, 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	957,53 MB/s	1,12 s
Program many small files	1167,01 MB/s	1,21 s
Game small and large files	1935,76 MB/s	0,71 s

Compression Performance Test

Here, the writing and reading speed of the the SanDisk SATA SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 530MB/s and 440MB/s respectively).

CrystalDiskMark Benchmark

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