I am looking for a network accessible storage solution. I am currently using a NAS to store backups. I am looking to set up another one somewhere else on the LAN. I will need the ability to add storage space to this NAS when necessary.
My question is, how to configure the new one when I pick it out. If I go with a NAS that has many drive bays, I am assuming that to expand storage space it is not as simple as inserting another drive if it is configured in some sort of RAID. All of the NAS I have seen so far have been running a RAID of some sort, and I like the idea of having some data redundancy in case a drive fails.
So in other words, I would like a NAS that I can run with some sort of a RAID configuration, but one that I can add storage space to if it fills up. If there is another option that is better I would be open to hear that. Also if anyone has a NAS that they recommend I would like to hear about that too.
