AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 12571 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	9490,18 MB/s	10491,90 MB/s
4K in megabytes per second	66,38 MB/s	207,80 MB/s
4K-64Thrd in megabytes per second	3196,76 MB/s	4912,89 MB/s
Access time in milliseconds	0,019 ms	0,200 ms

Total score	12571

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 October 01, 2024 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	5206,13 MB/s	0,44 s
Program many small files	1514,81 MB/s	4,65 s
Game small and large files	2957,44 MB/s	2,34 s

Compression Performance Test

Here, the writing and reading speed of the the Lexar SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 11500MB/s and 9000MB/s respectively).

CrystalDiskMark Benchmark

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