Oracle 19.11. RAC with ASM / OL7

We have to migrate 1TB of data to another RAC with ASM. There we have a diskgroup of 1.5TB size as target of data migration. Now I've to increase this DG with 1TB. Every disk in DG has external redundancy, same performance and the LUN size is 120GB.

My question regarding recommendations here:

- Should I add 2 new disks of 500G to this DG - or -
