AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 3394 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	3008,32 MB/s	2299,31 MB/s
4K in megabytes per second	64,36 MB/s	196,87 MB/s
4K-64Thrd in megabytes per second	720,68 MB/s	1341,68 MB/s
Access time in milliseconds	0,019 ms	0,108 ms

Total score	3394

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 July 18, 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	1823,97 MB/s	1,26 s
Program many small files	1183,98 MB/s	5,95 s
Game small and large files	1959,31 MB/s	3,53 s

Compression Performance Test

Here, the writing and reading speed of the the Transcend SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 3300MB/s and 2100MB/s respectively).

CrystalDiskMark Benchmark

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