AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 1862 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	1892,60 MB/s	1565,08 MB/s
4K in megabytes per second	41,83 MB/s	148,40 MB/s
4K-64Thrd in megabytes per second	372,29 MB/s	647,13 MB/s
Access time in milliseconds	0,025 ms	0,633 ms

Total score	1862

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 May 17, 2024 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	1841,42 MB/s	1,25 s
Program many small files	1165,94 MB/s	6,04 s
Game small and large files	1535,84 MB/s	4,50 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 1800MB/s and 1100MB/s respectively).

CrystalDiskMark Benchmark

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