I am about to build my first DIY NAS with unRaid. Currently I have a Synogoly DS9018+ with 4 x 6TB drives, another 2-bay Synology (3TB + 4TB drive) and an external 2TB drive. I have also bought 2x 4TB drives to put in the DIY box. My plan is to transfer data out of the DS918 to the other drives.
The motherboard has only 4x SATA connectors, a SATA expansion card is on its way, but will take probably a month to arrive.
Question is - can I build the NAS with the 2 new drives, transfer data from DS918, take them out for the moment, and build array with the 4x 6TB drives? The 'Unassigned Devices' plug-in seems like the way to go?
Would it be possible to then add them (the 2x 4TB drives) to the existing array keeping the data on them, or would the need to be re-formatted?
Thanks in advance!
