On one hand I have 2 HDDs with data, which are clones of one another I made using Cavalry Retriever duplicator. On another hand I have a brand new Patriot Javelin S4 NAS unit. I'm new to both RAID and NAS, but I figured that for my purposes I need RAID1 (2 mirrored drives, or if I get another pair of drives — 2 pairs of 2 mirrored drives).
Is there any way to have the drives setup in RAID1 without moving data out and back in again?
Disclosure: I don't actually have Javelin S4 yet, but it's shipped, and I can't find any info on this subject. Maybe all will be clear when I see its interface?
