AS SSD Benchmark

Standard performance test

The standard test was performed using 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
Score	4212	6170
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

This measures the write and read 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.

CDM	Read [MB/s]	Write [MB/s]
SEQ1M Q8T1	12363,70	12077,80
SEQ1M Q1T1	8310,16	8955,29
RND4K Q32T16	5487,90	4281,25
RND4K Q1T1	71,97	238,14

HD Tune Pro Endurance test

This is a long term test to make full use of the memory capacity. You can see when a cache is full and the writing performance decreases. A test file of 220 GB was written to the medium. The exact cache size could not be determined, because the test file did not exhaust the cache (brought it to the limit).At least the test file could be read with an average write speed of 10308 MB/s and written with 10523 MB/s.

HD Tune Pro Benchmark

HD Tune writes a 5 GB file to the Lexar M.2 SSD. The transfer data of the read speed is displayed graphically. The minimum, maximum and average values are also determined. The determined access time and burst rate are also displayed.

ATTO Disk Benchmark

Here, a 256 MB file is written several times to the Lexar M.2 SSD. The I/O block size varies (from 512 bytes to 64 megabytes). The larger the blocks, the faster they can be written and read.

SSD-Z Benchmark

Similar to HD Tune, a 500 MB file is written to the Lexar M.2 SSD here. The transfer data is displayed. The more constant the line, the better. Unfortunately the tool does not work correctly above about 5,000 MB/s and no line (and sometimes wrong min and max data) is displayed.

The benchmark test was performed on October 01, 2024.
