I believe the first step is to try to figure out about how much storage space you think you will need. If you don't think it is going to be all that much, say a TB or so, I'd just get 2 drives about 4-6 TB in size and mirror them. If you get two 6tb drives and mirror them, you end up with 6tb of usable space. For most folks that's quite a bit of storage. If you find that in a few years you start filling it up, you can swap them out for larger drives. Prices for larger drives a couple years from now will be far less than they are today.I personally like mirroring (Raid 1) much better than Raid 5, 7 or 10. With only 2 drives, there are far fewer things to fail or go wrong, they produce less heat and noise plus they use a lot less power to operate. If one drive fails, take it out, pop in a new one and the system will rebuild the new drive.
