AS SSD Benchmark

Standard performance test

The standard test was performed using a 1 GB file. A total score of 735 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	499,94 MB/s	451,55 MB/s
4K in megabytes per second	25,45 MB/s	86,46 MB/s
4K-64Thrd in megabytes per second	211,21 MB/s	163,22 MB/s
Access time in milliseconds	0,045 ms	0,141 ms
Score	287	295
Total score	735

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 17, 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	956,66 MB/s	1,12 s
Program many small files	1188,97 MB/s	1,18 s
Game small and large files	1613,85 MB/s	0,86 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 550 MB/s and 500 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	530,91	366,98
SEQ1M Q1T1	516,00	470,11
RND4K Q32T16	226,75	171,70
RND4K Q1T1	34,95	92,90

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 300 GB was written to the medium. After approx. 112 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 449 MB/s and written with 276 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 February 17, 2025.
