AS SSD Benchmark

Standard performance test

The standard test was performed using a 5 GB file. A total score of 3156 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	2694,86 MB/s	1967,38 MB/s
4K in megabytes per second	58,09 MB/s	181,13 MB/s
4K-64Thrd in megabytes per second	265,30 MB/s	1896,27 MB/s
Access time in milliseconds	0,022 ms	0,105 ms
Score	593	2274
Total score	3156

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 August 30, 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	1783,56 MB/s	1,29 s
Program many small files	1136,83 MB/s	6,19 s
Game small and large files	1894,86 MB/s	3,65 s

Compression Performance Test

This measures the write and read speed of the the Emtec SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 5000MB/s and 4400MB/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	4727,03	2052,72
SEQ1M Q1T1	2384,55	2033,74
RND4K Q32T16	798,50	2075,08
RND4K Q1T1	62,44	185,84

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 300 GB was written to the medium. After approx. 246 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 580 MB/s.

HD Tune Pro Benchmark

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

The benchmark test was performed on August 30, 2023.
