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

This SSD is PS5 compatible. It can be used as expansion storage in a PlayStation 5 console.

AS SSD Benchmark

Standard performance test

The standard test was performed using a 5 GB file. A total score of 7183 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	5978,04 MB/s	5574,43 MB/s
4K in megabytes per second	54,03 MB/s	182,11 MB/s
4K-64Thrd in megabytes per second	1771,90 MB/s	2800,83 MB/s
Access time in milliseconds	0,021 ms	0,109 ms
Score	2424	3540
Total score	7183

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 November 21, 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	2412,36 MB/s	0,95 s
Program many small files	1142,87 MB/s	6,16 s
Game small and large files	1883,26 MB/s	3,67 s

Compression Performance Test

This measures the write and read speed of the the Transcend SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 7100MB/s and 6500MB/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	7066,51	6489,60
SEQ1M Q1T1	4415,04	5304,18
RND4K Q32T16	2652,34	2704,21
RND4K Q1T1	57,62	181,63

HD Tune Pro Endurance test

This is a long term test 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 150 GB was written to the medium. After approx. 108 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 5669 MB/s and written with 1802 MB/s.

HD Tune Pro Benchmark

HD Tune writes a 5 GB file to the Transcend 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 Transcend 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 Transcend 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 above about 5,000 MB/s and no line (and sometimes wrong min and max data) is displayed.

The benchmark test was performed on November 21, 2023.
