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.
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.
The drive deals with large files much more efficiently than the smaller files of the 60GB Steam, 50GB File and 10GB Audio folders.
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 512GB Toshiba OCZ RD400
By taking the 6Gb/s interface of the Samsung drive out of the equation, we get a true idea of what the drive is capable of when dealing with our real life file transfers, particularly when dealing with the larger file sizes.
