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.
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.
Although the drive had no problems with our suite of real life file transfer tests, it much prefers dealing with large files than small bity files as can be seen with the results for the 60GB Steam, 50GB File and 10GB Audio folders when compared against any of the other tests.
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.
Taking the SATA based drive out of the equation produced some spectacular results, particularly when it came to handling the large files in the 12GB Movie, 4K and 8K folders and the 5GB image.
