AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 8415 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	5743,18 MB/s	5942,51 MB/s
4K in megabytes per second	63,77 MB/s	223,15 MB/s
4K-64Thrd in megabytes per second	1912,71 MB/s	3729,80 MB/s
Access time in milliseconds	0,016 ms	0,086 ms
Score	2551	4547
Total score	8415

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 January 12, 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	2137,54 MB/s	1,08 s
Program many small files	751,23 MB/s	9,37 s
Game small and large files	1533,23 MB/s	4,51 s

Compression Performance Test

Here, the writing and reading speed of the the Sabrent SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 7100MB/s and 6600MB/s respectively).

CrystalDiskMark Benchmark

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