Hi I recently just purchased latest iMac 5K with i7 , M395X + 512SSD. So storage media and editing is my main problem due to limited storage on the main drive (512SSD). My question is : Do you guy's edit photos or video (h.264 / 4k) through external storage drive directly ? will this coz any issue for lagging or life span for the external drive ? OR Just transfer the media to main SSD for editing , once completed then store in external storage ? So which way is your guy's preferred ? an d why ? Any recommendation for the external drive for particular usage (editing directly / storage only ?) Thank you very much.
