Need to add storage on my EX4

My Cloud OS 3 Personal & Network Attached Storage My Cloud EX4

I have an EX4 with two 4 TB red drives. They are configured with RAID1 set to mirror. I would like to add storage. What is the simplest way to add storage and retain my data? I was wondering if I should add two more 4 terabyte drives, but i would rather add an 8 TB drive and mirror that with the two fours that I have now if possible? I and not real familiar with RAID drives. So i need step by step instructions.

Thank You,

It depends on what RAID configuration you have. If you have 4 drives that are 4 TB each, then it may be difficult to do without replacing them with 4-8 TB drives. I would consider contacting Support for help with this.

Here is a compatibility list of drives
