I am pretty sure that I will be using a Thunderbay 6 by OWC as my primary storage solution(it will be connected to a Mac Mini with a Thunderbolt 2 adapter), however something like a Drobo is also a possiblity
What I am wrestling with is what will be my secondary storage that will be the backup for the RAID. The device is already going to the cloud so this is really about being able to recover from data loss in a reasonable amount of time and not downloading TBs of data. I initially thought I would go with a NAS solution but I then realized that I don't think having network connectivity will be possible for this device. Therefore I am rethinking my options.
I know there are NAS options that have USB connections so I may consider one of them (WD My Cloud Pro) but I am now wondering if another RAID solution makes more sense.
Any suggestions or advice are welcome. The capacity I am eying is 16TB but I could go to 12TB as well.
