AS SSD Benchmark

Standard performance test

The standard test was performed using a 5 GB file. A total score of 839 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	786,52 MB/s	678,59 MB/s
4K in megabytes per second	23,41 MB/s	61,26 MB/s
4K-64Thrd in megabytes per second	196,65 MB/s	255,28 MB/s
Access time in milliseconds	0,058 ms	0,622 ms
Score	299	384
Total score	839

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 23, 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	470,80 MB/s	4,88 s
Program many small files	120,84 MB/s	58,25 s
Game small and large files	333,17 MB/s	20,73 s

Compression Performance Test

This measures the write and read speed of the SSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 800MB/s and 800MB/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	845,52	724,87
SEQ1M Q1T1	751,46	656,54
RND4K Q32T16	198,77	329,64
RND4K Q1T1	27,23	67,01

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 130 GB was written to the medium. After approx. 120 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 807 MB/s and written with 554 MB/s.

HD Tune Pro Benchmark

HD Tune writes a 5 GB file to the Intenso 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 Intenso external SSD. 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 Intenso external SSD here. The transfer data is displayed. The more constant the line, the better.

The benchmark test was performed on February 23, 2023.
