AS SSD Benchmark

Standard performance test

The standard test was performed using a 5 GB file. A total score of 2846 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	2131,27 MB/s	1740,73 MB/s
4K in megabytes per second	50,83 MB/s	180,07 MB/s
4K-64Thrd in megabytes per second	676,35 MB/s	1075,04 MB/s
Access time in milliseconds	0,021 ms	0,180 ms
Score	940	1429
Total score	2846

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 30, 2021 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	1951,98 MB/s	1,18 s
Program many small files	760,16 MB/s	9,26 s
Game small and large files	1426,05 MB/s	4,84 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 2400MB/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	2313,12	1933,89
SEQ1M Q1T1	1570,15	1828,00
RND4K Q32T16	735,88	1236,92
RND4K Q1T1	55,90	206,97

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.

The benchmark test was performed on January 30, 2021.
