MycloudEX2Ultra - how to upgrade one drive?

Hi All, I have currently two 4 TB drives in my MycloudEX2Ultra, set up as 0 raid.

I want to upgrade one drive to 10tb, is there a way I can xfer data from one drive to the new drive automatically and keep the second old drive as it is- again keep it as 0 raid

Thanks

Anybody able to help please?

While technically possible, it isn’t worth it to upgrade one drive.
After the upgrade, you will have 14 TB of raw storage.
Since you are using RAID 0, you still only will have 8 TB of storage together. You only get the size of the smallest drive
