AS SSD Benchmark

Standard performance test

The standard test was performed with a 1 GB file. A total score of 92 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	215,23 MB/s	26,00 MB/s
4K in megabytes per second	12,98 MB/s	10,84 MB/s
4K-64Thrd in megabytes per second	13,10 MB/s	10,57 MB/s
Access time in milliseconds	0,163 ms	0,591 ms
Score	48	24
Total score	92

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 24, 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	25,03 MB/s	42,91 s
Program many small files	20,75 MB/s	67,82 s
Game small and large files	23,91 MB/s	57,76 s

Compression Performance Test

Here, the writing and reading speed of the the Samsung USB flash driveSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 200MB/s and 25MB/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	225,71	33,50
SEQ1M Q1T1	226,07	34,78
RND4K Q32T16	14,80	13,52
RND4K Q1T1	13,58	13,66

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 32 GB Samsung 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 Samsung 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 32 GB Samsung USB flash drive here. is written. The transfer data is displayed. The more constant the line, the better.

The benchmark test was performed on December 24, 2020.
