Re: So, if an enterprise buys ten 200GB SSDs it could then choose not to buy fifty 200GB HDDs.
Enterprise SAS drives still come in such sizes.

Re: Lithium ion eh?
Actually if handled properly they can outlive a lead acid battery. You also forget the power density is much better with lithium and they can handle the load to a much lower state of charge than lead acid too. If you charge them to 80% they will last 4x longer than if you charge them to 100%. They also don't care what state of charge they're kept at where as lead acid must be kept at 100% to prevent sulfation of the cells.
It is true though that deep discharging any lead acid or lithium battery is bad for it, but lithium batteries nearly always have protection against this built into them as they become unstable if deep discharged. Similarly with over charging, they are often protected.
