I am currently running a HP Proliant N36L (4 disks) with the following setup:
Disk 1: 160GB HDD that came with the Proliant N36L as system disk (latest version of OMV)
Disk 2: Raid 1 - WD Green 1TB
Disk 3: Raid 1 - WD Green 1TB
Disk 4: Internal backup - 1TB Seagate (I think, not sure which model)
2x Seagate portable USB HDD which I use for weekly backups (rotated - so each every 2 weeks).
Now I am getting closer and closer to the 1TB. At the moment the disks have around 725GB on them.
So I was looking around for 2TB disks. I heard that the Green series from WD is actually not made for NAS servers, but to be honest, I am running them for more than 2 years in my little machine and there was never a problem. I know that the RED series is made for NAS, but they are so much more expensive here (Brazil). --> WD Green 2TB about R$ 300-350, WD Red 2TB R$ 600 and above.
What HD do you recommend? I am rather looking for an inexpensive solution, but of course I don't want to buy disks that are known for breaking quickly.
Another question: How would you move the data to the new Disks??
