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

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

AS SSD Benchmark

Standard performance test

The standard test was performed using a 5 GB file. A total score of 13013 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	10811,50 MB/s	11365,40 MB/s
4K in megabytes per second	79,05 MB/s	276,94 MB/s
4K-64Thrd in megabytes per second	3244,15 MB/s	4925,54 MB/s
Access time in milliseconds	0,014 ms	0,203 ms
Score	4404	6339
Total score	13013

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 March 13, 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	5022,81 MB/s	0,46 s
Program many small files	1658,62 MB/s	4,24 s
Game small and large files	3213,13 MB/s	2,15 s

Compression Performance Test

This measures the write and read speed of the the Crucial SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 14500MB/s and 12700MB/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	14481,20	12746,90
SEQ1M Q1T1	9087,48	10411,90
RND4K Q32T16	5417,13	4100,01
RND4K Q1T1	772,42	550,56

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 240 GB was written to the medium. After approx. 224 GB, the pSLC-Cache was full and the performance was throttled.
At least the test file could be read with an average write speed of 10968 MB/s and written with 9951 MB/s.

HD Tune Pro Benchmark

HD Tune writes a 5 GB file to the Crucial 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 Crucial 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 Crucial 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 March 13, 2024.
