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 6410 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	5803,72 MB/s	3765,95 MB/s
4K in megabytes per second	75,13 MB/s	207,41 MB/s
4K-64Thrd in megabytes per second	1406,85 MB/s	2796,73 MB/s
Access time in milliseconds	0,018 ms	0,091 ms
Score	2062	3381
Total score	6410

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 September 19, 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	2311,43 MB/s	0,99 s
Program many small files	1137,69 MB/s	6,19 s
Game small and large files	1932,12 MB/s	3,58 s

Compression Performance Test

Here, the writing and reading speed of the the Sabrent SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 7000MB/s and 3500MB/s respectively).

CrystalDiskMark Benchmark

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