AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 2021 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	1782,11 MB/s	921,17 MB/s
4K in megabytes per second	55,77 MB/s	174,59 MB/s
4K-64Thrd in megabytes per second	378,78 MB/s	850,80 MB/s
Access time in milliseconds	0,027 ms	0,112 ms
Score	613	1118
Total score	2021

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 September 06, 2022 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	1460,79 MB/s	1,57 s
Program many small files	917,81 MB/s	7,67 s
Game small and large files	911,11 MB/s	7,58 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 2000MB/s and 1000MB/s respectively).

CrystalDiskMark Benchmark

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