AS SSD Benchmark

Standard performance test

The standard test was performed using a 5 GB file. A total score of 4291 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	2987,92 MB/s	2828,42 MB/s
4K in megabytes per second	59,72 MB/s	177,53 MB/s
4K-64Thrd in megabytes per second	981,45 MB/s	1799,13 MB/s
Access time in milliseconds	0,021 ms	0,134 ms
Score	1340	2260
Total score	4291

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 January 06, 2023 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	1856,49 MB/s	1,24 s
Program many small files	1224,07 MB/s	5,75 s
Game small and large files	1810,52 MB/s	3,82 s

Compression Performance Test

This measures the write and read speed of the the MSI SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 3300MB/s and 2300MB/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	3480,91	3123,15
SEQ1M Q1T1	2169,28	2963,40
RND4K Q32T16	1612,98	2361,57
RND4K Q1T1	63,15	184,25

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 200 GB was written to the medium. After approx. 115 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 1754 MB/s and written with 308 MB/s.

HD Tune Pro Benchmark

HD Tune writes a 5 GB file to the MSI 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 MSI 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 MSI M.2 SSD here. is written. The transfer data is displayed. The more constant the line, the better.

The benchmark test was performed on January 06, 2023.
