AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 3596 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	3125,97 MB/s	1758,06 MB/s
4K in megabytes per second	50,53 MB/s	159,05 MB/s
4K-64Thrd in megabytes per second	1079,31 MB/s	1140,57 MB/s
Access time in milliseconds	0,073 ms	0,117 ms
Score	1442	1475
Total score	3596

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 August 18, 2021 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	2190,58 MB/s	1,05 s
Program many small files	1328,86 MB/s	5,30 s
Game small and large files	1886,03 MB/s	3,66 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 3500MB/s and 2000MB/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	3526,09	1830,27
SEQ1M Q1T1	2666,42	1827,20
RND4K Q32T16	1200,55	1120,36
RND4K Q1T1	52,76	168,37

HD Tune Pro Endurance test

A long-term test was performed here to make full use of the memory capacity. You can see when a cache is full and the writing performance decreases.

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. is written. The transfer data is displayed. The more constant the line, the better.

The benchmark test was performed on August 18, 2021.
