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 7211 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	5819,77 MB/s	6063,19 MB/s
4K in megabytes per second	63,90 MB/s	214,95 MB/s
4K-64Thrd in megabytes per second	1565,37 MB/s	3028,41 MB/s
Access time in milliseconds	0,017 ms	0,088 ms
Score	2211	3850
Total score	7211

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 July 24, 2024 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	1995,07 MB/s	1,15 s
Program many small files	1151,98 MB/s	6,11 s
Game small and large files	1870,30 MB/s	3,69 s

Compression Performance Test

Here, the writing and reading speed of the the KIOXIA SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 7300MB/s and 6300MB/s respectively).

CrystalDiskMark Benchmark

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