I'm considering purchasing a NAS, a Synology DS216 (or perhaps a DS216j).
I have 2x 2TB drives available; one is full of data; the other is blank. I want to use the NAS in a RAID-1 configuration, to replicate the data from drive 1 to drive 2, and use them for backups going forward.
I'm on a Mac: the drives are formatted HFS+.
Will these two drives be sufficient with this equipment? Will I be able to insert both drives into the NAS, and be off to the races?
On the other hand, would I have to reformat the drives for use, or otherwise risk losing the data on the full HD? In this case, is it better to start with two blank drives, and copy my data post-setup?
Thanks.
