*) Test result evaluated according to AS SSD Score within the same size.

This SSD is PS5 compatible. It can be used as expansion storage in a PlayStation 5 console.

AS SSD Benchmark

Standard performance test

The standard test was performed using a 5 GB file. A total score of 8122 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	6197,27 MB/s	5736,79 MB/s
4K in megabytes per second	71,88 MB/s	182,36 MB/s
4K-64Thrd in megabytes per second	2364,00 MB/s	2770,07 MB/s
Access time in milliseconds	0,021 ms	0,111 ms
Score	3056	3526
Total score	8122

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 November 19, 2022 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	2122,79 MB/s	1,08 s
Program many small files	1220,14 MB/s	5,77 s
Game small and large files	1847,55 MB/s	3,74 s

Compression Performance Test

This measures the write and read speed of the ADATA SSD, depending on the compressibility of the data (according to the manufacturer, these should be 7400 MB/s and 6000 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	7434,20	6667,52
SEQ1M Q1T1	4182,93	5494,28
RND4K Q32T16	2975,76	2705,85
RND4K Q1T1	63,08	179,98

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. 128 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 6386 MB/s and written with 4103 MB/s.

HD Tune Pro Benchmark

HD Tune writes a 5 GB file to the ADATA M.2 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 M.2 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 M.2 SSD here. The transfer data is displayed. The more constant the line, the better. Unfortunately, the tool does not work correctly above about 5,000 MB/s and no line (and sometimes wrong min and max data) is displayed.

The benchmark test was performed on November 19, 2022.
