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.

We use the following folder/file types:

• 100GB data file.
• 60GB iso image.
• 60GB Steam folder – 29,521 files.
• 50GB File folder – 28,523 files.
• 12GB Movie folder – (15 files – 8 @ .MKV, 4 @ .MOV, 3 @ MP4).
• 10GB Photo folder – (304 files – 171 @ .RAW, 105 @ JPG, 21 @ .CR2, 5 @ .DNG).
• 10GB Audio folder – (1,483 files – 1479 @ MP3, 4 @ .FLAC files).
• 5GB (1.5bn pixel) photo.
• BluRay Movie – 42GB.
• 21GB 8K Movie demos – (11 demos)
• 16GB 4K Raw Movie Clips – (9 MP4V files).
• 4.25GB 3D Printer File Folder – (166 files – 105 @ .STL, 38 @ .FBX, 11 @ .blend, 5 @ .lwo, 4 @ .OBJ, 3@ .3ds).
• 1.5GB AutoCAD File Folder (80 files – 60 @ .DWG and 20 @.DXF).

The WD Ultrastar DC HC560 20TB drive had no problems dealing with any of our real-life file transfers and produced pretty consistent performance when it came to handling the larger file sizes with an average write figure for the seven large file transfers of 270MB/s with reads at 196MB/s. The slowest of the file transfers was the 50GB File Folder, full of small bity files, with writes at 154MB/s and reads at 157MB/s.
