> Our database runs on 3 servers (1 primary, 2 secondaries), each with two 480GB SSDs in a RAID 1 configuration Algorithmically cool, but quite a lot of work to save <$500/yr in hardware for a handful of 1TB SSDs. Converting the data to the new format cost more than upgrading disks. |

If rate of growth is disk usage is at or below the rate of growth in mid-tier SSDs, then yes, it's $500/yr. If you are growing faster than that, then an improvement might be saving you $350/yr + $150/yr², and a wall in the future might be pushed out for years.
With your Cloud provider, it might be hard to get more disk, memory, or CPU without paying for more of the other two. Also, many real organizations and vendor agreements are full of the most stupid artificial constraints. Just because someone else can build a 1PB SSD storage array doesn't mean that any of my coworkers will be allowed to build one any time soon. CAPEX austerity measures are among the most frustrating penny-wise pound-foolish policies we have to deal with.
