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.
We use the following folder/file typesL
- 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 1TB Toshiba BG4 handled our real life file transfer tests without missing a beat. It's much more efficient at dealing with larger file sizes than small bity ones as can be seen by the results for the 60GB Steam, 50GB file and 10GB audio tests.
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 512GB Toshiba OCZ RD400:
Transferring the files to and from another NVMe drive shows just how quick the BG4 is at handling file transfers especially when it comes to reading the data.
