AS SSD Benchmark 2.0

Standard performance test

The standard test was performed with a 1 GB file. Here, a total score of 0 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	125,82 MB/s	27,45 MB/s
4K in megabytes per second	0,00 MB/s	0,00 MB/s
4K-64Thrd in megabytes per second	0,00 MB/s	0,00 MB/s
Access time in milliseconds	0,000 ms	0,000 ms
Score	0	0
Total score	0

With an AS SSD total score of 0 (zero), the AS SSD benchmark could not be completed. The reason for this are extremely poor 4K values. These are around 0.01 MB/s, so the benchmark tool would need days to pass the 1 GB test. Such USB sticks are rather not suitable for everyday use. It is better to invest few Dollars more in a stick with better 4K rates.

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 Windows Copy command (the cache remains enabled). The practical test of 28.10.2021 shows the performance for simultaneous write and read operations. The lower the duration, the better.

AS SSD Kopier-Benchmark	Transferrate:	Dauer:
ISO two large files	24,27 MB/s	44,26 s
Program many small files	7,32 MB/s	192,10 s
Game small and large files	16,12 MB/s	85,67 s

Compression Performance Test

Here, the write as well as read speed (according to the manufacturer 200 MB/s and 100 MB/s) the HP USB flash drive is measured depending on the compressibility of the data.

CrystalDiskMark 7.0 Benchmark

Similar to AS SSD, two sequential and two random performance tests are performed.

ATTO Disk Benchmark 4

Here a 256 MB file is written several times to the 128 GB HP USB flash drive. The I/O block size varies (from 512 bytes to 64 megabytes). The larger the blocks, the faster they can usually be written and read.

HD Tune Pro 5.75 Benchmark

HD Tune writes a 1 GB file to the 128 GB HP 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.

HD Tune Endurance test

A long-term test was performed here to fully utilize the memory. You can see when a cache is full and the write performance decreases.

SSD-Z 16 Benchmark

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

The benchmark test was performed on 28.10.2021. Information about the test system can be found at the bottom of the home page.
