AS SSD Benchmark

Standard performance test

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

AS SSD TEST: Kingston DataTraveler SE9 G2 64GB

AS SSD	Read:	Write:
Seq in megabytes per second	108,74 MB/s	32,06 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 is that the 4K values were extremely poor - around 0.01 MB/s - so the benchmark tool would need days to pass the 1 GB test. Such USB memory sticks are not suitable for everyday use and it is better to invest a little more in a drive 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 the Windows Copy command (the cache remains enabled). The practical test of December 03, 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	28,84 MB/s	37,24 s
Program many small files	6,55 MB/s	214,87 s
Game small and large files	16,08 MB/s	85,88 s

Compression Performance Test

Here, the writing and reading speed of the the Kingston USB flash driveSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 100MB/s and 15MB/s respectively).

CrystalDiskMark Benchmark

Here, two sequential and two random performance tests are performed, similar to the ones performed on the AS SSD.

HD Tune Pro Benchmark

HD Tune writes a 1 GB file to the 64 GB Kingston 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 64 GB Kingston 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 December 03, 2020.
