...PC power and disk space.
After handling over 1000 D850 nefs, with hangs and long waiting times, I realise I have to go shopping.
My 5 year old PC(i7-2600k,16Gb ram, sabertoothP67, 2nd gen SSD's), can't do this job decently.
Up to that, Nikon software, which I prefer, slows everything down even more...
Kindest regards,
Stany
