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.
The CS3030 handled our real life transfer tests without any problems. It's much happier dealing with large file sizes than smaller bity files.
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 drive out of the loop, the drive shows some excellent performance when dealing with the large files in the 4K movie and 12GB Movie folders and the 5GB photo.
