I've noticed that I made an error the RNAS314 has 4 x 5TB and the EDA500 has 2 x 5TB drives.

I posted a more thorough reply that now seems to be gone. Won't do that again.

But I recommand for your EDA at least 5TB HDD and to put raid5!

Yes. But you could switch to flexraid and create a separate volume with the 3 TB drives.
