AS SSD Benchmark

Standard performance test

The standard test was performed using a 5 GB file. A total score of 908 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	999,87 MB/s	917,79 MB/s
4K in megabytes per second	20,76 MB/s	59,33 MB/s
4K-64Thrd in megabytes per second	296,49 MB/s	124,40 MB/s
Access time in milliseconds	0,215 ms	0,301 ms
Score	417	276
Total score	908

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 28, 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	574,13 MB/s	4,00 s
Program many small files	73,06 MB/s	96,34 s
Game small and large files	250,42 MB/s	27,59 s

Compression Performance Test

This measures the write and read speed of the external SSD from Samsung, depending on the compressibility of the data (according to the manufacturer, these should be 1050 MB/s and 1000 MB/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	1091,14	1031,39
SEQ1M Q1T1	811,04	879,88
RND4K Q32T16	323,04	137,49
RND4K Q1T1	21,49	64,46

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 100 GB was written to the medium. After approx. 80 GB, the pSLC-Cache was full and the performance was throttled.
At least the test file could be read with an average write speed of 1030 MB/s and written with 832 MB/s.

HD Tune Pro Benchmark

HD Tune writes a 5 GB file to the Samsung external SSD. 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 Samsung external SSD. The I/O block size varies (from 512 bytes to 64 megabytes). The larger the blocks, the faster they were written and read.

SSD-Z Benchmark

Similar to HD Tune, a 500 MB file is written to the Samsung external SSD here. The transfer data is displayed. The more constant the line, the better.

The benchmark test was performed on February 28, 2023.
