I am setting up a NAS box, but money is a bit short right now. I am planning on getting the box up and running with a boot drive, then 3 for a RAID 5 config with some lower end drives.
I was reading online about a bunch of the complications that can arise from people not setting it up right, and couldn't get a feeling of exactly how hard/feasible it would be.
- Is it possible to upgrade (replace a drive with a bigger/faster one) and/or add drives (without wiping, and rebuilding)?
- How risky is it to do this with data that isn't backed up (because of sheer volume)?
- Any tips/advice I should follow to set up a best case in the future to allow upgrades?
Note, I'm really between a RAID 5, and a RAID 01. Would this be easier to upgrade a RAID 01?
