AS SSD Benchmark

Standard performance test

The standard test was performed using a 5 GB file. A total score of 6189 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	3234,30 MB/s	3033,82 MB/s
4K in megabytes per second	70,42 MB/s	207,01 MB/s
4K-64Thrd in megabytes per second	1946,26 MB/s	2143,33 MB/s
Access time in milliseconds	0,017 ms	0,099 ms
Score	2340	2654
Total score	6189

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 February 23, 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	2352,11 MB/s	0,98 s
Program many small files	1158,30 MB/s	6,08 s
Game small and large files	1936,34 MB/s	3,57 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 3500MB/s and 1900MB/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	3669,65	3340,26
SEQ1M Q1T1	2730,61	3051,57
RND4K Q32T16	3133,29	2585,04
RND4K Q1T1	74,76	239,10

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 100 GB was written to the medium. After approx. 64 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 3317 MB/s and written with 1056 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. is written. The transfer data is displayed. The more constant the line, the better.

The benchmark test was performed on February 23, 2024.
