AS SSD Benchmark

Standard performance test

The standard test was performed using a 5 GB file. A total score of 6835 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	4491,88 MB/s	3966,25 MB/s
4K in megabytes per second	60,99 MB/s	177,14 MB/s
4K-64Thrd in megabytes per second	2151,66 MB/s	2264,06 MB/s
Access time in milliseconds	0,020 ms	0,466 ms
Score	2662	2838
Total score	6835

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 30, 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	2262,72 MB/s	1,02 s
Program many small files	1143,11 MB/s	6,16 s
Game small and large files	1919,53 MB/s	3,60 s

Compression Performance Test

This measures the write and read speed of the Lexar SSD, depending on the compressibility of the data (according to the manufacturer, these should be 5300 MB/s and 4500 MB/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	5243,74	4721,91
SEQ1M Q1T1	3714,25	4173,68
RND4K Q32T16	3038,66	2631,70
RND4K Q1T1	78,71	193,19

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 300 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 3650 MB/s and written with 3738 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 were 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.

The benchmark test was performed on August 30, 2024.
