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 an 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.
- 21GB 8K Movie demos.
- 12GB Movie folder – 24 files (mix of Blu-ray and 4K files).
- 11GB 4K Raw Movie Clips (8 MP4V 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.
- Blu-ray movie.
The DiskStation DS120j tackles our real life file transfer tests without too many problems.
