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 6832 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	5136,39 MB/s	5759,33 MB/s
4K in megabytes per second	57,76 MB/s	202,85 MB/s
4K-64Thrd in megabytes per second	1682,52 MB/s	2612,08 MB/s
Access time in milliseconds	0,015 ms	0,420 ms
Score	2254	3391
Total score	6832

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 January 16, 2021 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	2215,84 MB/s	1,04 s
Program many small files	177,37 MB/s	39,68 s
Game small and large files	1550,32 MB/s	4,46 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 6400 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	7459,60	6744,26
SEQ1M Q1T1	3241,08	5685,16
RND4K Q32T16	2432,73	3361,82
RND4K Q1T1	62,75	231,35

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.

The benchmark test was performed on January 16, 2021.
