Golf cart for your commute, anyone?
When you buy a new car, you balance your budget against features an performance, but if I offered you a BMW for the price of a budget family car, which would you buy? There wouldn't be many people saying it's too fast!
That's where we are going with SSD. Next year, at some point, we'll see SDD get as cheap as the cheapest hard drive. With lifetimes well beyond any realistic wear-out, and better reliability, would you buy another hard drive in 2017? You'd be nuts...or you'd swallowed all that FUD hook, line and sinker.
Reality is that we are already making a dumb comparison. SSD are cheaper today than "enterprise" hard drives., and come in much larger capacities. The enterprise HDD is already dead!
