RN214 replacing hard disks
Dear All, I am using my ReadyNas RN214 with 3x2TB disks in Raid 0 mode (eg. 6TB) with no redundancy, so I want to replace them 2x6TB wd red series for upgrade. I have checked with RAID calcul...
Since you have configured the 3 HDDs you have to RAID-0 then for you to be able to use X-RAID you will have to destroy the volume or do a factory reset and start from scratch.
You will have to backup all your data first, then turn off your NAS and replace/insert the new drives (2x6TB, 2x2TB). You can then perform a Factory reset from the Boot Menu.

This will reset the NAS and reformat the drives and be configured to X-RAID RAID5.

My advice is to avoid the WD60EFAX, because it is an SMR drive. Get the older WD60EFRX, or move up to the 8 TB Reds (which use PMR).
SMR drives will give uneven performance with write speeds, and there are some scenarios where raid resync or expansion can be extremely slow.

Correct. Then insert all your drives, and do a factory default procedure via the boot menu. Reconfigure the NAS, and then restore your files from the backup.
