AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 5210 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	4213,55 MB/s	2394,54 MB/s
4K in megabytes per second	55,70 MB/s	81,34 MB/s
4K-64Thrd in megabytes per second	1338,79 MB/s	2228,23 MB/s
Access time in milliseconds	0,022 ms	0,102 ms

Total score	5210

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 28, 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	2123,42 MB/s	1,08 s
Program many small files	1223,44 MB/s	5,75 s
Game small and large files	1812,84 MB/s	3,81 s

Compression Performance Test

Here, the writing and reading speed of the the PNY SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 5600MB/s and 2600MB/s respectively).

CrystalDiskMark Benchmark

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