I've been doing some shuffling of data to some new drives and installation to a new system. The problem i have is that I've not quite got enough internal disks or system infrastructure in my home environment to simply copy all my data from the old to the new, so I'm having to do it bit by bit (no pun intended). I've come to a minor conundrum; and my question is: is it better to
a. Add 2 empty disks to a pool, turn on duplication and then copy the data to the new pool and let it duplicate as it copies the data to the pool?
or
b. Copy the data to a new single disk, then add another disk to the pool and turn on duplication?
Option b is going to be slightly less risky for me as it means I have less data to shuffle round and am able to another copy of it while I an writing to the new pool. I can then check and make sure there is no issue before wiping the other drive and adding it to the poo, although it might then take a long time to duplicate the data (about 2.5 TB). I suspect option a will be more efficient, as it will simultaneously write to 2 disks, rather than to one then duplicating to another later on, but are there any other issues / pros / cons? Any help greatly appreciated!
