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).

SanDisk's Extreme Pro SSD didn’t have any real problems dealing with our real-life file transfer tests. It handles larger file sizes much more efficiently than smaller ones that make up the 60GB Steam, 50GB File and 10GB Audio folders.

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 Kioxia RD400:

Transferring files to and from another NVMe drive saw read speeds of over 900MB/s for the folders containing larger file sizes. The drive did seem to stumble when transferring the 5GB photo back to the RD400.
