AS SSD Benchmark

Standard performance test

The standard test was performed using a 1 GB file. A total score of 698 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	431,57 MB/s	264,34 MB/s
4K in megabytes per second	42,48 MB/s	83,71 MB/s
4K-64Thrd in megabytes per second	178,51 MB/s	179,07 MB/s
Access time in milliseconds	0,042 ms	0,142 ms
Score	264	289
Total score	698

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 15, 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	701,28 MB/s	1,53 s
Program many small files	1204,64 MB/s	1,17 s
Game small and large files	1363,65 MB/s	1,01 s

Compression Performance Test

This measures the write and read speed of the PNY SATA SSD, depending on the compressibility of the data (according to the manufacturer, these should be 535 MB/s and 515 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	472,99	314,95
SEQ1M Q1T1	444,00	315,68
RND4K Q32T16	180,87	195,03
RND4K Q1T1	35,76	87,93

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 1 GB file to the PNY 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 PNY SATA 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 PNY SATA SSD here. The transfer data is displayed. The more constant the line, the better.

The benchmark test was performed on November 15, 2022.
