*) 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 7873 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	9328,17 MB/s	10675,50 MB/s
4K in megabytes per second	71,41 MB/s	216,90 MB/s
4K-64Thrd in megabytes per second	1452,83 MB/s	2799,85 MB/s
Access time in milliseconds	0,017 ms	0,089 ms
Score	2457	4084
Total score	7873

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 August 05, 2025 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	4199,60 MB/s	0,55 s
Program many small files	1307,07 MB/s	5,39 s
Game small and large files	2649,65 MB/s	2,61 s

Compression Performance Test

Here, the writing and reading speed of the the Biwin SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 14000MB/s and 13000MB/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	14206,30	13513,30
SEQ1M Q1T1	5636,86	9868,54
RND4K Q32T16	5805,02	4398,61
RND4K Q1T1	76,12	241,44

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 400 GB was written to the medium. After approx. 390 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 8803 MB/s and written with 10825 MB/s.

ATTO Disk Benchmark

Here, a 256 MB file is written several times to the Biwin 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 Biwin 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 August 05, 2025.
