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 Lexar MN610 had no real problems dealing with our real-life file transfer tests with the exception of when the 100GB data file is being written to it when it seemed to struggle somewhat. Apart from this file, the drive is much more efficient at handling larger file sizes, with over 500GB/s speeds, than the smaller files found in the 60GB Steam, 50GB file and 10GB audio folders.
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 SSD out of the picture gives a better idea of just how capable the NM610 is at dealing with real-life file transfers, but once again the drive has a problem with the 100GB data file.
