*) 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 7981 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	5949,83 MB/s	5729,38 MB/s
4K in megabytes per second	65,22 MB/s	179,80 MB/s
4K-64Thrd in megabytes per second	2405,45 MB/s	2608,40 MB/s
Access time in milliseconds	0,020 ms	0,352 ms
Score	3066	3361
Total score	7981

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 29, 2024 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	2429,93 MB/s	0,95 s
Program many small files	1215,75 MB/s	5,79 s
Game small and large files	1930,00 MB/s	3,58 s

Compression Performance Test

This measures the write and read speed of the the KingSpec SSD, depending on the compressibility of the data (according to the manufacturer, these should be 7400 MB/s and 6600 MB/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	7438,13	6760,82
SEQ1M Q1T1	3793,03	5101,37
RND4K Q32T16	3662,83	2958,81
RND4K Q1T1	82,96	197,53

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 200 GB was written to the medium. The exact cache size could not be determined, because the test file did not exhaust the cache (brought it to the limit).At least the test file could be read with an average write speed of 5006 MB/s and written with 5673 MB/s.

HD Tune Pro Benchmark

HD Tune writes a 5 GB file to the KingSpec 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 KingSpec M.2 SSD. The I/O block size varies (from 512 bytes to 64 megabytes). The larger the blocks, the faster they were written and read.

SSD-Z Benchmark

Similar to HD Tune, a 500 MB file is written to the KingSpec M.2 SSD here. 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 29, 2024.
