I am new to FreeNAS, again. I used FreeNAS many years ago but stopped using it in favor of a more energy efficient Buffalo Link Station. My network storage needs were and still are simple. The Link Station is full, 500 gigs, along with the add on USB drives, another 500 gigs. The Link Station is showing signs it is about to quit. I have set up my old PC that has a quad core 2.8 gig processor, 8 gigs of RAM for FreeNAS. I have done everything except install my storage drives. I bought 2 1 terabyte drives with the intent of installing them as separate drives. Now looking at the directions for the set up of storage it would seem I can only have a raid configuration. I don't want a stripe configuration to get 2 gigs of storage. The next viable option for me would be a mirror, but this won't get more storage for me. Is returning my hard drives for bigger ones my only option? If I mirror the two 1 gig drives and then add more drives later, do I use the additional drives and extend the current ZFS volume or can I have an additional ZFS Pool? Which would be better? How would the storage appear on the network? As two separate drives?
