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 8521 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	5943,98 MB/s	5599,14 MB/s
4K in megabytes per second	70,56 MB/s	175,75 MB/s
4K-64Thrd in megabytes per second	2660,64 MB/s	2778,68 MB/s
Access time in milliseconds	0,020 ms	0,110 ms
Score	3326	3514
Total score	8521

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 December 05, 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	1879,63 MB/s	1,22 s
Program many small files	1233,84 MB/s	5,70 s
Game small and large files	1819,73 MB/s	3,80 s

Compression Performance Test

Here, the writing and reading speed of the the Samsung SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 7450MB/s and 6900MB/s respectively).

CrystalDiskMark Benchmark

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