Add Second Disk Sunrise, If there are empty drive slots on your Synology NAS, you can install additional drives and add them to an existing storage pool. This blog guides you through how to add additional drives and create a raid. Initially, I added a second 4 TB disk in an empty slot. I already have one 4TB hard disk installed in my sinology NAS and I have my data in it too.
What is RAID click here
RAID configuration must be created by drives of the same type. Using disks of different types will affect system reliability and performance.
Mixed drive types are not supported for RAID configuration.
The capacity of the disk you need to add must be similar to or larger than the smallest drive in the storage pool.
