AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 5490 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	2987,02 MB/s	2510,37 MB/s
4K in megabytes per second	51,89 MB/s	177,86 MB/s
4K-64Thrd in megabytes per second	1340,78 MB/s	2522,29 MB/s
Access time in milliseconds	0,027 ms	0,106 ms
Score	1691	2951
Total score	5490

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 14, 2022 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	1741,81 MB/s	1,32 s
Program many small files	1206,64 MB/s	5,83 s
Game small and large files	1809,52 MB/s	3,82 s

Compression Performance Test

Here, the writing and reading speed of the the Sabrent SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 3400MB/s and 2000MB/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	3454,52	2644,23
SEQ1M Q1T1	2165,45	2644,48
RND4K Q32T16	1736,80	2613,40
RND4K Q1T1	54,77	190,96

HD Tune Pro Endurance test

A long-term test was performed here to make full use of the memory capacity. You can see when a cache is full and the writing performance decreases.

HD Tune Pro Benchmark

HD Tune writes a 5 GB file to the Sabrent 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 Sabrent 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 Sabrent 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 14, 2022.
