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.
- 100GB data file.
- 60GB iso image.
- 60GB Steam folder – 29,521 files.
- 50GB File folder – 28,523 files.
- 12GB Movie folder – 24 files (mix of Blu-ray and 4K 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.
- BluRay movie.
In our real-life file transfer tests, the WD Black P40 Game Drive averaged 379.61MB/s for the thirteen transfers when writing data was being written to the drive. The fastest write performance was the 543MB/s for the 5GB image. Reading the data back, the drive averaged 417.69MB/s, the fastest transfer being the 12GB Movie Folder.
To get a measure of how much faster PCIe NVMe drives are than standard SATA SSDs we use the same files but transferred to and from a 2TB Kioxia Exceria Plus drive:
Switching over to reading and writing the data to another NVMe drive saw, as you might expect dramatic leaps in performance, particularly when it came to reading the data from the drive,
