AS SSD Benchmark

Standard performance test

The standard test was performed using a 5 GB file. A total score of 2752 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	2718,08 MB/s	1238,24 MB/s
4K in megabytes per second	61,25 MB/s	153,78 MB/s
4K-64Thrd in megabytes per second	774,62 MB/s	856,11 MB/s
Access time in milliseconds	0,033 ms	0,731 ms
Score	1108	1134
Total score	2752

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 February 03, 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	1563,98 MB/s	1,47 s
Program many small files	1068,10 MB/s	6,59 s
Game small and large files	1188,68 MB/s	5,81 s

Compression Performance Test

This measures the write and read speed of the Mushkin SSD, depending on the compressibility of the data (according to the manufacturer, these should be 3100 MB/s and 1400 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	3009,37	1276,75
SEQ1M Q1T1	1887,63	1285,07
RND4K Q32T16	828,93	997,83
RND4K Q1T1	65,42	185,02

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 100 GB was written to the medium. After approx. 52 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 629 MB/s and written with 496 MB/s.

HD Tune Pro Benchmark

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

The benchmark test was performed on February 03, 2023.
