*) Test result evaluated according to AS SSD Score within the same size.

This SSD is PS5 compatible. It can be used in a PlayStation 5 console as expansion storage.

AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 8325 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	5955,96 MB/s	5419,35 MB/s
4K in megabytes per second	79,40 MB/s	195,89 MB/s
4K-64Thrd in megabytes per second	2487,49 MB/s	2830,78 MB/s
Access time in milliseconds	0,017 ms	0,104 ms
Score	3162	3569
Total score	8325

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 10, 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	1792,52 MB/s	1,28 s
Program many small files	1261,49 MB/s	5,58 s
Game small and large files	1878,94 MB/s	3,68 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 7500MB/s and 6300MB/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	7465,22	6268,19
SEQ1M Q1T1	3418,64	5265,60
RND4K Q32T16	3755,93	2859,88
RND4K Q1T1	85,28	210,90

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. Unfortunately the tool does not work correctly from about 5,000 MB/s and no line (and partly wrong min and max data) is displayed.

The benchmark test was performed on December 10, 2022.
