AS SSD Benchmark

Standard performance test

The standard test was performed using a 1 GB file. A total score of 586 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	510,39 MB/s	439,28 MB/s
4K in megabytes per second	20,18 MB/s	81,70 MB/s
4K-64Thrd in megabytes per second	121,16 MB/s	165,27 MB/s
Access time in milliseconds	0,168 ms	0,202 ms
Score	192	291
Total score	586

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 03, 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	910,16 MB/s	1,18 s
Program many small files	1120,32 MB/s	1,26 s
Game small and large files	1439,30 MB/s	0,96 s

Compression Performance Test

This measures the write and read speed of the ADATA SATA SSD, depending on the compressibility of the data (according to the manufacturer, these should be 520 MB/s and 450 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	540,19	453,79
SEQ1M Q1T1	526,32	446,51
RND4K Q32T16	128,30	178,19
RND4K Q1T1	21,56	88,56

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 150 GB was written to the medium. After approx. 124 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 475 MB/s and written with 111 MB/s.

HD Tune Pro Benchmark

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

The benchmark test was performed on February 03, 2025.
