AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 1083 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	945,38 MB/s	905,45 MB/s
4K in megabytes per second	26,68 MB/s	88,27 MB/s
4K-64Thrd in megabytes per second	258,43 MB/s	323,69 MB/s
Access time in milliseconds	0,082 ms	0,210 ms
Score	380	502
Total score	1083

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 January 31, 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	622,36 MB/s	3,69 s
Program many small files	430,94 MB/s	16,33 s
Game small and large files	569,45 MB/s	12,13 s

Compression Performance Test

Here, the writing and reading speed of the SSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 1050MB/s and 1050MB/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	1052,18	1014,20
SEQ1M Q1T1	830,87	957,97
RND4K Q32T16	297,53	400,26
RND4K Q1T1	38,12	96,69

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 300 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 1003 MB/s and written with 973 MB/s.

HD Tune Pro Benchmark

HD Tune writes a 5 GB file to the Crucial external 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 Crucial external 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 Crucial external SSD here. is written. The transfer data is displayed. The more constant the line, the better.

The benchmark test was performed on January 31, 2023.
