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 a drive reading from & writing to a 256GB Samsung SSD850 PRO.
We use the following folder/file types:
- 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.
The Exceria Pro was a solid performer when it came to our real-life file transfers particularly when dealing with the larger file size transfers, averaging 546MB/s for writes and 450MB/s for reads when dealing with these file types.
To get a measure of how much faster PCIe NVMe drives are than standard SATA SSDs we use the same files but transfer to and from a 2TB Kioxia Exceria Plus drive:
Switching over to NVMe to NVMe file transfers saw the bandwidths rocket upwards and transfer times drop dramatically. Five of the write speeds topped 3GB/s, the fastest being the 3,100MB/s for the 60GB iso image while nine of the read transfers topped 2GB/s, the fastest being the 8K movie scenes folder at 2,794MB/s
