Hi folks!!
It may be a newbie question, but I would like to get some help designing a small media server with Unraid. Currently, I use my home PC with 4 SATA drives without RAID as both my home pc, gaming machine and Plex server. With the growth of my library, I decided to build a dedicated media server that can be up 24/7, because my gaming PC chugs electricity like there's no tomorrow.
But I have no familiarity with RAID or Unraid. I plan to buy 3 new 4TB SATA drives for storage, add one of my own 4TB HDDs, leaving one of the new HDDs as a parity drive. I understand, from the docs, that a 4TB parity drive limits my upgrades to 4TB parity drives, right? Then I have a few questions:
Do I need to wipe clean my 4TB HDD to include it on the array? Or can I set up an array with 2 clean HDDs + 1 parity drive and then include my filled-up HDD to the array without data loss?
Would it be better to just start the array with 2+1 drives, copy my data to the array, and then wiping the HDD to add it cleanly to the array?
Is it possible to upgrade the parity drive in the future to a, let's say, 12TB drive and then add another 10TB disk to the array?
I consider myself pretty tech savvy, and I'm familiar with the linux command line. This, however, is waaay out of my league, I've never done anything similar.
