As a Newbie I would ask a tool for data transfert from actual NAS/HDD storage
A way to put an existing NAS/SATA drive already full of data into an array (with index rebuild)
It would be so useful when switch between NAS and Unraid
Otherwise a direct data transfer between units (USB/eSata/ect) into the array
This because low end user (like me) won't be too expensive with network devices/home device
