Asustor AS5202T Nimbustor 2 2-bay NAS Review

To test real life file/folder performance we use a number of different file/folder combinations to test the read and write performance of the NAS device. Using the FastCopy utility to get a MB/s and time taken for each transfer, the data is written from and read back to a 240GB SSD.

We use the following file/folder types:

• 100GB data file.
• 60GB iso image.
• 60GB Steam folder – 29,521 files.
• 50GB File folder – 28,523 files.
• 12GB Movie folder – 24 files (mix of Blu-ray and 4K files).
• 10GB Photo folder – 621 files (mix of .png, raw and .jpeg images).
• 10GB Audio folder – 1,483 files (mix of mp3 and .flac files).
• 5GB (1.5bn pixel) photo.
• BluRay Movie.
• 21GB 8K Movie demos.
• 11GB 4K Raw Movie Clips (8 MP4V files).

The AS5202T dealt with our real life file transfer tests with ease. With a 2.5GbE connection we got over well over 200MB/s transfer rates for most of the tests, with the exception of the ones dealing with folders containing a lot of small-sized files. The 60GB Steam and 10GB Audio folders produced over 100MB/s for read and writes which is much faster than the transfer rates for the same tests with a 1GbE connection. For the 50GB file transfer tests there wasn't that much of a difference between the two connection speeds in either RAID array.
