AS SSD Benchmark

Standard performance test

The standard test was performed using a 5 GB file. A total score of 3908 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	5856,73 MB/s	1279,96 MB/s
4K in megabytes per second	50,13 MB/s	246,42 MB/s
4K-64Thrd in megabytes per second	1233,88 MB/s	932,67 MB/s
Access time in milliseconds	0,015 ms	0,075 ms
Score	1870	1307
Total score	3908

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 26, 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	1781,83 MB/s	1,29 s
Program many small files	1015,84 MB/s	6,93 s
Game small and large files	1272,80 MB/s	5,43 s

Compression Performance Test

This measures the write and read speed of the the Kingston SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 7000MB/s and 1300MB/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	7424,07	1300,01
SEQ1M Q1T1	2365,60	1343,81
RND4K Q32T16	3795,54	1156,82
RND4K Q1T1	52,69	266,19

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 2041 MB/s and written with 1263 MB/s.

HD Tune Pro Benchmark

HD Tune writes a 5 GB file to the Kingston 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 Kingston 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 Kingston M.2 SSD here. The transfer data is displayed. The more constant the line, the better.

The benchmark test was performed on August 26, 2024.
