AS SSD Benchmark

Standard performance test

The standard test was performed with a 1 GB file. A total score of 63 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	151,77 MB/s	134,73 MB/s
4K in megabytes per second	6,23 MB/s	1,58 MB/s
4K-64Thrd in megabytes per second	8,43 MB/s	1,34 MB/s
Access time in milliseconds	0,387 ms	1,977 ms
Score	30	16
Total score	63

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 October 22, 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	46,09 MB/s	23,30 s
Program many small files	10,08 MB/s	139,60 s
Game small and large files	39,97 MB/s	34,55 s

Compression Performance Test

Here, the writing and reading speed of the the Hama USB flash driveSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 40MB/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	159,29	143,17
SEQ1M Q1T1	159,48	141,34
RND4K Q32T16	21,93	1,93
RND4K Q1T1	10,38	2,33

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 1 GB file to the 128 GB Hama 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 128 GB Hama 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.

SSD-Z Benchmark

Similar to HD Tune, a 500 MB file is written to the 128 GB Hama USB flash drive here. is written. The transfer data is displayed. The more constant the line, the better.

The benchmark test was performed on October 22, 2020.
