Question about parity


Recommended Posts

Hi,

 

I'm trying to build a NAS. I came across unRAID and I had a simple question about upgrading my hard drives in the future.

 

I intended on buy 3 2TB drives and from my understanding, one of the drives will be used as a parity.

My question is what if I want to add a 3TB drive in the future? What would happen to my array?

The 3TB drive would become your new parity drive, and your old parity drive would become data disk3.  This is known as 'parity swap' in the unRAID world.  Your effective capacity would increase from 4 TB to 6 TB.  If you added a second 3 TB drive as a data disk, your capacity would increase from 6 TB to 9 TB.  Make sense?
