I am planning on buying a DS920+ for home and business use. I run a software consulting business from home. Typically only 2 people will access the NAS and our storage needs are low (no plex, video, or surveillance needs). I chose the DS920+ as an investment in something that is scalable that I won't need to upgrade for a long time. (Tell me if I should reconsider this.) Considering I currently have low storage needs, what is the best strategy for hard drive selection? Do I populate all 4 bays with hard drives or only 2 or 3 bays? What size do I buy- the largest I can afford? Do I buy the same size for all hard drives or maybe 1 large and 2 smaller sizes? Ideally, I spend no more than $600 USD (around the same price as the NAS) for hard drives. How do I best allocate this?
