AS SSD Benchmark

Standard performance test

The standard test was performed using a 5 GB file. A total score of 6779 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	4394,87 MB/s	3422,92 MB/s
4K in megabytes per second	64,53 MB/s	169,08 MB/s
4K-64Thrd in megabytes per second	2302,30 MB/s	2074,62 MB/s
Access time in milliseconds	0,023 ms	0,117 ms
Score	2806	2586
Total score	6779

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 March 25, 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	2344,70 MB/s	0,98 s
Program many small files	1128,82 MB/s	6,24 s
Game small and large files	1951,73 MB/s	3,54 s

Compression Performance Test

This measures the write and read speed of the the Samsung SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 5000MB/s and 4200MB/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	5087,50	3723,78
SEQ1M Q1T1	2864,00	3707,21
RND4K Q32T16	3139,30	2466,69
RND4K Q1T1	69,76	193,29

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. 120 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 2743 MB/s and written with 1454 MB/s.

HD Tune Pro Benchmark

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

The benchmark test was performed on March 25, 2024.
