AS SSD Benchmark

Standard performance test

The standard test was performed using a 1 GB file. A total score of 606 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	518,34 MB/s	440,07 MB/s
4K in megabytes per second	20,99 MB/s	81,62 MB/s
4K-64Thrd in megabytes per second	135,91 MB/s	160,73 MB/s
Access time in milliseconds	0,040 ms	0,158 ms
Score	209	286
Total score	606

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 19, 2020 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	937,17 MB/s	1,15 s
Program many small files	724,48 MB/s	1,94 s
Game small and large files	1125,17 MB/s	1,23 s

Compression Performance Test

This measures the write and read speed of the the Transcend SATA SSDSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 550MB/s and 500MB/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	549,93	460,45
SEQ1M Q1T1	537,92	451,72
RND4K Q32T16	218,30	171,01
RND4K Q1T1	32,47	90,51

HD Tune Pro Benchmark

HD Tune writes a 1 GB file to the Transcend SATA 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 Transcend SATA 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.

The benchmark test was performed on November 19, 2020.
