We're pulling a bunch of things (GBs) off of our network storage and archiving it onto external HDDs. Copies are made of each external HDD so that one can go off-site and one can stay here. Is there a way to mirror the two drives (RAID 1?) and copy the data to both at the same time?

Sans Digital makes some nice small raid enclosures, high quality, been using one for 5 years, very happy with – Moab Aug 10 '11 at 21:29

I'd suggest you just roll with a simple rsync script for this. Nice thing about not going RAID is then you don't have to worry about the particular RAID implementation you elect actually handles a missing disk... Granted that should work okay anyway..

+1 for not having to worry about the RAID implications. – Hennes Dec 10 '15 at 13:17
