AS SSD Benchmark

Standard performance test

The standard test was performed using a 1 GB file. A total score of 77 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	265,25 MB/s	49,07 MB/s
4K in megabytes per second	10,49 MB/s	2,76 MB/s
4K-64Thrd in megabytes per second	10,85 MB/s	2,85 MB/s
Access time in milliseconds	0,383 ms	1,439 ms
Score	48	11
Total score	77

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 April 08, 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	36,77 MB/s	29,20 s
Program many small files	21,79 MB/s	64,57 s
Game small and large files	31,52 MB/s	43,81 s

Compression Performance Test

This measures the write and read speed of the the Kingston USB flash driveSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 200MB/s and 60MB/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	279,40	65,41
SEQ1M Q1T1	276,19	60,67
RND4K Q32T16	13,96	5,00
RND4K Q1T1	11,13	3,74

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 April 08, 2021.
