AS SSD Benchmark

Standard performance test

The standard test was performed using a 1 GB file. A total score of 229 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	385,05 MB/s	109,44 MB/s
4K in megabytes per second	12,84 MB/s	25,60 MB/s
4K-64Thrd in megabytes per second	13,24 MB/s	102,68 MB/s
Access time in milliseconds	0,140 ms	0,478 ms
Score	65	139
Total score	229

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 11, 2023 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	106,51 MB/s	10,08 s
Program many small files	67,41 MB/s	20,87 s
Game small and large files	95,35 MB/s	14,48 s

Compression Performance Test

This measures the write and read speed of the the Samsung USB flash driveSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 400MB/s and 110MB/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	408,60	113,86
SEQ1M Q1T1	406,23	115,59
RND4K Q32T16	14,24	21,60
RND4K Q1T1	13,14	27,44

HD Tune Pro Endurance test

This is a long term test to make full use of the memory capacity. You can see when a cache is full and the writing performance decreases. A test file of 50 GB was written to the medium.

HD Tune Pro Benchmark

HD Tune writes a 1 GB file to the 256 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 256 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 256 GB Samsung USB flash drive here. The transfer data is displayed. The more constant the line, the better.

The benchmark test was performed on December 11, 2023.
