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, [email protected] .3ds).
- 1.5GB AutoCAD File Folder (80 files – 60 @ .DWG and 20 @.DXF).
The Black D50 Game Dock didn’t have any real problems dealing with our real-life file transfer tests. It handles writes of larger file sizes much more efficiently than reads but as usual its the smaller files that make up the 60GB Steam, 50GB File and 10GB Audio folders that slow the drive down.
To get a measure of how much faster PCIe NVMe drives are than standard SATA SSDs we use the same files but transfer to and from a 512GB Toshiba OCZ RD400:
Taking the SATA drive out of the loop shows just how fast the WD Black D50 Game can perform, although the 60GB Steam, 50GB File and 10GB Audio folder transfers are still slow compared to the large file transfers.
