I have a WD My Cloud PR4100 NAS 2x8TB (2x WD 8TB Red 5400 rpm HDDs) running OS3 with RAID-1, bought it approx. 3 years ago. Recently I decided to purchase 2x WD 8TB Red 5400 rpm HDDs.
My desire is to extend my storage from 8TB to 16TB.
Since I’m currently running RAID-1, my question is "Can I extend my PR4100 to obtain a total of 16TB RAID, and if so, what would be the recommended steps to successfully upgrade my storage from 8TB to 16TB?
Please note that I do not want to lose any data on my current 2x8TB HDDs.
Please note that I do not wish to upgrade the OS from OS3 to OS5.
Please note that I was directed to this subforum. I was told to see the dedicated subforum for the Pro Series of devices where users more familiar with that device (PR4100) who may be able to assist.
Thank you in advance.
