AS SSD Benchmark

Standard performance test

The standard test was performed using a 1 GB file. A total score of 41 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	145,94 MB/s	40,34 MB/s
4K in megabytes per second	5,65 MB/s	0,49 MB/s
4K-64Thrd in megabytes per second	5,05 MB/s	0,71 MB/s
Access time in milliseconds	1,302 ms	9,860 ms
Score	25	5
Total score	41

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 26, 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	17,07 MB/s	62,92 s
Program many small files	10,30 MB/s	136,65 s
Game small and large files	15,69 MB/s	88,02 s

Compression Performance Test

This measures the write and read speed of the the SanDisk USB flash driveSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 150MB/s and 40MB/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	150,99	43,49
SEQ1M Q1T1	150,97	43,38
RND4K Q32T16	7,46	1,91
RND4K Q1T1	7,06	1,79

HD Tune Pro Benchmark

HD Tune writes a 1 GB file to the 32 GB SanDisk USB flash drive. 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 32 GB SanDisk USB flash drive. 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 26, 2021.
