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.
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 drive was very consistent when dealing with the six larger file transfers in our real-life file transfer tests averaging 543MB/s when writing to the drive and 447MB/s when reading them back.
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:
Reading and writing to another NVMe drive saw, as you might expect, transfer speeds to rocket upwards with an average write speed for the same six transfers as before up to 3,060MB/s (the fastest transfer being for the 60GB iso file). The average read speed for the same transfers was 2,454MB/s, the fastest transfer being the 12GB Movie folder.
