AS SSD Benchmark

Standard performance test

The standard test was performed using a 1 GB file. A total score of 665 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	498,40 MB/s	424,28 MB/s
4K in megabytes per second	29,21 MB/s	84,81 MB/s
4K-64Thrd in megabytes per second	161,04 MB/s	166,49 MB/s
Access time in milliseconds	0,041 ms	0,168 ms
Score	240	294
Total score	665

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 March 15, 2025 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	1024,42 MB/s	1,05 s
Program many small files	951,25 MB/s	1,48 s
Game small and large files	1480,35 MB/s	0,93 s

Compression Performance Test

This measures the write and read speed of the Integral SATA SSD, depending on the compressibility of the data (according to the manufacturer, these should be 450 MB/s and 400 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	528,69	445,51
SEQ1M Q1T1	529,20	436,39
RND4K Q32T16	233,73	177,76
RND4K Q1T1	46,06	90,22

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. 87 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 460 MB/s and written with 286 MB/s.

HD Tune Pro Benchmark

HD Tune writes a 1 GB file to the Integral SATA 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 Integral SATA 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 Integral SATA SSD here. The transfer data is displayed. The more constant the line, the better.

The benchmark test was performed on March 15, 2025.
