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 types:
- 100GB data file.
- 60GB iso image.
- 60GB Steam folder – 29,521 files.
- 50GB File folder – 28,523 files.
- 12GB Movie folder – (15 files – 8 @ .MKV, 4 @ .MOV, 3 @ MP4).
- 10GB Photo folder – (304 files – 171 @ .RAW, 105 @ JPG, 21 @ .CR2, 5 @ .DNG).
- 10GB Audio folder – (1,483 files – 1479 @ MP3, 4 @ .FLAC files).
- 5GB (1.5bn pixel) photo.
- BluRay Movie – 42GB.
- 21GB 8K Movie demos – (11 demos)
- 16GB 4K Raw Movie Clips – (9 MP4V files).
- 4.25GB 3D Printer File Folder – (166 files – 105 @ .STL, 38 @ .FBX, 11 @ .blend, 5 @ .lwo, 4 @ .OBJ, 3@ .3ds).
- 1.5GB AutoCAD File Folder (80 files – 60 @ .DWG and 20 @.DXF).
The Gigabyte Aorus 7000s 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, averaging 515MB/s when writing to the drive and 443MB/s when reading the data back. As usual, it’s 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 SSDs we use the same files but transfer to and from a 2TB Kioxia Exceria Plus drive:
Switching over to an all NVMe storage environment saw transfer speeds for the large file transfers rocket and times taken drop dramatically. Eleven out of the thirteen write tests topped well over 2GB/s with five passing the 2.5GB/s mark. Nine of the read tests also passed 2GB/s, the best being the 2.57GB/s figure for reading the back of the 4K movie clips folder.
