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

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 8575 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	6017,14 MB/s	4908,95 MB/s
4K in megabytes per second	74,82 MB/s	206,25 MB/s
4K-64Thrd in megabytes per second	2562,35 MB/s	3037,46 MB/s
Access time in milliseconds	0,018 ms	0,092 ms
Score	3239	3735
Total score	8575

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 May 10, 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	2091,06 MB/s	1,10 s
Program many small files	1183,59 MB/s	5,95 s
Game small and large files	1985,23 MB/s	3,48 s

Compression Performance Test

Here, the writing and reading speed of the the Intel SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 7000MB/s and 4700MB/s respectively).

CrystalDiskMark Benchmark

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