I use booth a Nikon D700 and a D4s, and when I’m importing the files to my internal PC hard drive i got completely different transfer rate speeds from the 2 cameras cards.
I import the files via a Transcend RDF8 card Reader (USB 3.0) to my computer through the USB 3.0 port and using the Windows 7 explorer.
For example, the same 8GB Sandisk Extreme Pro CF card in both cameras, gave me this results:
D700: Full card loaded with +/- 290 files (NEF + JPG). Transfer rate speed to computer around 30 MB/s and takes about 4 min to import all the files!
D4s: Full card loaded with +/- 190 files (NEF + JPG). Transfer rate speed to computer around 14 MB/s and takes about 12 min to import all the files!
If the card capacity and speed is the same, why there there’s this difference in speed rates from the files of the D700 and D4s? Does anyone have a clue?
Thanks,
