*) 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 9086 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	5951,49 MB/s	5740,95 MB/s
4K in megabytes per second	70,27 MB/s	174,13 MB/s
4K-64Thrd in megabytes per second	2801,79 MB/s	3112,25 MB/s
Access time in milliseconds	0,020 ms	0,112 ms
Score	3467	3860
Total score	9086

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	1978,54 MB/s	1,16 s
Program many small files	1219,93 MB/s	5,77 s
Game small and large files	1836,15 MB/s	3,76 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.

CDM	Read [MB/s]	Write [MB/s]
SEQ1M Q8T1	7459,60	6849,32
SEQ1M Q1T1	3344,89	5564,42
RND4K Q32T16	3613,20	2723,42
RND4K Q1T1	74,23	179,14

HD Tune Pro Endurance test

A long-term test was performed here to make full use of the memory capacity. You can see when a cache is full and the writing performance decreases. A test file of 250 GB was written to the medium. After approx. 230 GB, the pSLC-Cache was full and the performance was throttled.
At least the test file could be read with an average write speed of 5949 MB/s and written with 4664 MB/s.

HD Tune Pro Benchmark

HD Tune writes a 5 GB file to the Samsung M.2 SSD. The transfer data of the read speed is displayed graphically. The minimum, maximum and average values are also determined. The determined access time and burst rate are also displayed.

ATTO Disk Benchmark

Here, a 256 MB file is written several times to the Samsung M.2 SSD . The I/O block size varies (from 512 bytes to 64 megabytes). The larger the blocks, the faster they can be written and read.

SSD-Z Benchmark

Similar to HD Tune, a 500 MB file is written to the Samsung M.2 SSD here. is written. The transfer data is displayed. The more constant the line, the better. Unfortunately the tool does not work correctly from about 5,000 MB/s and no line (and partly wrong min and max data) is displayed.

The benchmark test was performed on December 05, 2022.
