To test real-life performance of a drive we use a mix of folder/file types and by using the FastCopy utility (which gives a time as well as MB/s result) we record the performance of drive reading from & writing to a 256GB Samsung SSD850 PRO.
100GB data file.
60GB iso image.
50GB File folder – 28,523 files.
21GB 8K Movie demos.
11GB 4K Raw Movie Clips (8 MP4V files).
4.25GB 3D Printer File Folder (mostly .STL).
1GB AutoCAD File Folder (.dwg and .dxf).
Our real-life file transfer tests posed little problem for the DC500R as it handled most of them very efficiently. As always it's the 50GB file folder transfer that slows down the drive.
