Migration issue from Xpenology

[nicolas246]

Hi,

I am now running an Xpenology and want to switch to Unraid.
My current NAS has 4 drives, 3x3TB and 1x4TB in Synology Hybrid Raid, one redundant drive.
As i am looking to expand it with a 1 x10 TB drive i now consider switching to Unraid. Xpnoolgy is stuck on an old version and upgrading sucks.

 

So the question,

If i get a new nas, put that 10 TB drive in there, copy all the files over from the old NAS, wipe those 4 drives, can i then insert them into the new NAS and add them to the drive pool creating some sort of raid with a 1 drive redundancy?

 

If so that redundancy will eat up a part of my 10 TB drive and make most of the storage on that drive redundant? As the other drives are much smaller.

 

I want to move from NAS A to B and I am not sure how much new drives I need.
Is 1 x 10TB enough to then add the other four to create a raid?

Is the 10TB going to be wasted on the other muchg smaller disks?

 

If you can help me, it would be much appreciated.

Unraid IS NOT RAID.

 

Each disk is an independent filesystem. Redundancy is provided by 1 or 2 parity drives. 

 

No data drive can be larger than any parity drive.
