> Further you would ideally need two of them to remove single point of failure.

That's assuming that everything needs to be 'high availability' and buying two of everything is a must. This is definitely not always the case. In plenty of situations buying a single item and simply repairing it when it breaks is a perfectly good strategy.




Its not about having two of everything at all times, but rather about having a capacity whenever you need it. At 244Gb you hit a sweet point where you can have access to large capability at a flexible price (Spot Market / On Demand / On Premise). This is what separates engineers with business acumen from run of the mill "consultants" with a search engine.


You mentioned 'single point of failure'.
