To test the 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.
• 21GB 8K Movie demos.
• 12GB Movie folder – 24 files (mix of Blu-ray and 4K files).
• 11GB 4K Raw Movie Clips (8 MP4V files).
• 10GB Photo folder – 621 files (mix of png, raw and jpeg images).
• 10GB Audio folder – 1,483 files (mix of mp3 and .flac files).
• 5GB (1.5bn pixel) photo.
• Blu-ray movie.

The WD Blue SN570 handled our real-life file testing without displaying any problems averaging 513MB/s writing the larger test files to the drive and 441MB/s when reading the data back again.

To get a measure of how much faster PCIe NVMe drives are than standard SATA SSD's we use the same files but transfer to and from a 2TB Kioxia Exceria Plus drive:

Switching over to an all NVMe storage environment we see write speeds averaging 2,422MB/s for the six largest folder transfers, the fastest being the 2,645MB/s when writing the 5GB image.
