AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 7018 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	5730,28 MB/s	5255,47 MB/s
4K in megabytes per second	66,51 MB/s	221,19 MB/s
4K-64Thrd in megabytes per second	1274,62 MB/s	3390,48 MB/s
Access time in milliseconds	0,017 ms	0,086 ms
Score	1914	4137
Total score	7018

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 June 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	2324,79 MB/s	0,99 s
Program many small files	1182,84 MB/s	5,95 s
Game small and large files	1906,95 MB/s	3,62 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 7000MB/s and 5300MB/s respectively).

CrystalDiskMark Benchmark

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