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).

Our real-life file transfers didn’t cause the Synology SNV3400-400G any real problems. It was very consistent when writing the larger file sizes to disk. It also handled the small bity files of the 10GB Audio, 50GB file and 60GB Steam folders reasonable well.

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:

Using the NVMe drive to transfer the files to and from the SNV400-400G saw the read speeds dramatically increase while the write speeds increase was very small in comparison, but the performance was still very consistent when dealing with the larger file sizes.
