In the conclusion they mentioned rate of growth as well.
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.
