To test the 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.
Blu-ray movie.
Sabrent’s Rocket 4 Plus dealt with our real-life file transfers without any problems, showing very good consistency of performance for both reads and writes when dealing with the larger file sizes, although as usual its the small files in the Audio, Steam and File folders that cause the drive to slow down.
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.
Switching over to the NVMe drive to transfer data to and from the 2TB Rocket 4 Plus saw transfer speeds for the large file transfers rocket and times taken drop dramatically. Six of the transfers topped well over 2.5 GB/s for writing to the drive.
