AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 2531 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	2326,20 MB/s	1754,37 MB/s
4K in megabytes per second	43,92 MB/s	166,72 MB/s
4K-64Thrd in megabytes per second	702,58 MB/s	727,00 MB/s
Access time in milliseconds	0,021 ms	0,603 ms

Total score	2531

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 08, 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	1627,90 MB/s	1,41 s
Program many small files	1129,47 MB/s	6,23 s
Game small and large files	1660,44 MB/s	4,16 s

Compression Performance Test

Here, the writing and reading speed of the the Apacer SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 2100MB/s and 1500MB/s respectively).

CrystalDiskMark Benchmark

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