AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 4725 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	3025,92 MB/s	2591,35 MB/s
4K in megabytes per second	47,87 MB/s	177,49 MB/s
4K-64Thrd in megabytes per second	1356,58 MB/s	1725,69 MB/s
Access time in milliseconds	0,023 ms	0,112 ms
Score	1707	2162
Total score	4725

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 03, 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	1860,00 MB/s	1,24 s
Program many small files	727,36 MB/s	9,68 s
Game small and large files	1548,87 MB/s	4,46 s

Compression Performance Test

Here, the writing and reading speed of the the Western Digital SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 3470MB/s and 3000MB/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	3436,73	3107,00
SEQ1M Q1T1	2274,76	3018,19
RND4K Q32T16	1997,38	2276,94
RND4K Q1T1	47,05	198,75

HD Tune Pro Benchmark

HD Tune writes a 5 GB file to the Western Digital 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 Western Digital 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 February 03, 2021.
