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

AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 6570 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	5870,40 MB/s	3852,54 MB/s
4K in megabytes per second	76,92 MB/s	206,04 MB/s
4K-64Thrd in megabytes per second	1465,47 MB/s	2847,43 MB/s
Access time in milliseconds	0,017 ms	0,089 ms
Score	2129	3439
Total score	6570

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 28, 2023 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	1751,06 MB/s	1,31 s
Program many small files	1240,08 MB/s	5,68 s
Game small and large files	1852,02 MB/s	3,73 s

Compression Performance Test

Here, the writing and reading speed of the the Kingston SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 7000MB/s and 3900MB/s respectively).

CrystalDiskMark Benchmark

Here, two sequential and two random performance tests are performed, similar to the ones performed on the AS SSD.
