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 the drive reading from & writing to a 256GB Samsung SSD850 PRO.
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).
The dip in performance of writing the contents of the 50GB file folder and the 60GB Steam folder is shown up in the times both activities took to complete, the 50GB folder took ten minutes and the 60GB Steam folder ten and a half minutes.
