AS SSD Benchmark

Standard performance test

The standard test was performed using a 1 GB file. A total score of 0 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	112,41 MB/s	40,99 MB/s
4K in megabytes per second	5,70 MB/s	0,11 MB/s
4K-64Thrd in megabytes per second	0,00 MB/s	0,00 MB/s
Access time in milliseconds	0,000 ms	0,000 ms
Score	0	0
Total score	0

The AS SSD benchmark could not be completed with an overall score of 0 (zero). The reason for this is that the 4K values were extremely poor - around 0.01 MB/s - and the benchmark tool would take days to pass the 1 GB test. Such USB sticks are not suitable for everyday use and it is better to invest a little more in a drive with better 4K rates.

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 July 22, 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	36,36 MB/s	29,54 s
Program many small files	14,43 MB/s	97,52 s
Game small and large files	30,30 MB/s	45,58 s

Compression Performance Test

This measures the write and read speed of the the Netac USB flash driveSSD is measured depending on the compressibility of the data (according to the manufacturer, these should be 120MB/s and 0MB/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	119,67	46,03
SEQ1M Q1T1	120,96	45,71
RND4K Q32T16	10,25	0,13
RND4K Q1T1	6,14	0,17

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 Endurance Test TEST: Netac UM3 32GB

HD Tune Pro Benchmark

HD Tune writes a 1 GB file to the 32 GB Netac USB flash drive. 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 32 GB Netac USB flash drive. 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 32 GB Netac USB flash drive here. The transfer data is displayed. The more constant the line, the better.

The benchmark test was performed on July 22, 2024.
