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).

Real-life file transfers saw read performance go over the 500MB/s mark on a few occasions when transferring data from a SATA drive, peaking at the 554MB/s when writing the 5GB image to the T7 Shield.

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.

But the true potential of the drive was shown when transferring data to and from an NVMe SSD when we saw read transfer rates as high as 1,095MB/s for five of the large file transfers.
