AS SSD Benchmark

Standard performance test

The standard test was performed using a 5 GB file. A total score of 795 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	778,83 MB/s	724,88 MB/s
4K in megabytes per second	25,58 MB/s	89,04 MB/s
4K-64Thrd in megabytes per second	157,95 MB/s	231,03 MB/s
Access time in milliseconds	0,061 ms	0,220 ms
Score	261	393
Total score	795

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 18, 2022 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	570,04 MB/s	4,03 s
Program many small files	15,33 MB/s	459,12 s
Game small and large files	64,47 MB/s	107,16 s

Compression Performance Test

This measures the write and read speed of the external SSD from Crucial, depending on the compressibility of the data (according to the manufacturer, these should be 800 MB/s and 800 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	853,76	772,82
SEQ1M Q1T1	663,09	774,00
RND4K Q32T16	170,84	338,02
RND4K Q1T1	37,27	97,64

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.

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 were written and read.

SSD-Z Benchmark

Similar to HD Tune, a 500 MB file is written to the Crucial external SSD here. The transfer data is displayed. The more constant the line, the better.

The benchmark test was performed on November 18, 2022.
