Dabbling in photography for 45 years… Nikon, Nikkor and Tamron are my favorite gear. Also a licensed drone pilot for aerial photo and video using only DJI drones and gear… I currently use WD My Cloud EX4100 and PR4100 both with 24TB capacity and the PR4100 has 16GB of RAM installed… Because of the digital media I create, using just external or internal HD it is not as efficient or productive as having the 2 NAS systems for backup of media…
