AS SSD Benchmark

Standard performance test

The standard test was performed with a 1 GB file. A total score of 636 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	504,82 MB/s	442,54 MB/s
4K in megabytes per second	25,32 MB/s	86,57 MB/s
4K-64Thrd in megabytes per second	146,19 MB/s	162,48 MB/s
Access time in milliseconds	0,045 ms	0,152 ms

Total score	636

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 December 07, 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	886,70 MB/s	1,21 s
Program many small files	1262,88 MB/s	1,11 s
Game small and large files	1448,47 MB/s	0,95 s

Compression Performance Test

Here, the writing and reading speed of the the Lexar SATA SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 550MB/s and 480MB/s respectively).

CrystalDiskMark Benchmark

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