AS SSD Benchmark

Standard performance test

The standard test was performed using a 5 GB file. A total score of 3689 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	2726,80 MB/s	1870,55 MB/s
4K in megabytes per second	54,58 MB/s	165,86 MB/s
4K-64Thrd in megabytes per second	662,24 MB/s	1866,95 MB/s
Access time in milliseconds	0,028 ms	0,112 ms
Score	989	2220
Total score	3689

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 June 30, 2020 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	1746,74 MB/s	1,32 s
Program many small files	750,91 MB/s	9,37 s
Game small and large files	1445,07 MB/s	4,78 s

Compression Performance Test

This measures the write and read speed of the the Sabrent SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 3200MB/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	3094,85	1942,75
SEQ1M Q1T1	1954,99	1926,07
RND4K Q32T16	798,78	1938,01
RND4K Q1T1	59,77	182,87

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.

The benchmark test was performed on June 30, 2020.
