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	Read:	Write:
Seq in megabytes per second	132,54 MB/s	13,03 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

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 17, 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	12,29 MB/s	87,42 s
Program many small files	7,61 MB/s	184,83 s
Game small and large files	10,47 MB/s	131,92 s

Compression Performance Test

Here, the writing and reading speed of the the Kioxia USB flash driveSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 0MB/s and 0MB/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	139,87	8,80
SEQ1M Q1T1	139,73	14,85
RND4K Q32T16	14,72	0,00
RND4K Q1T1	14,00	0,00

HD Tune Pro Benchmark

HD Tune writes a 1 GB file to the 32 GB Kioxia 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 Kioxia 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 17, 2021.
