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:
10GB data file.
15GB 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.
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).
Kingston's IronKey Keypad 200 had no problems dealing with our real-life file transfers. It averaged 67.2MB/s for writes, the fastest being the 111MB/s writing the AutoCAD folder, the slowest being the 50GB File folder transfer at 29MB/s. Reads averaged 114MB/s with the fastest being the 169MB/s obtained when transferring the 5GB image and the slowest was once again the 50GB File folder transfer.
