Most consumers make purchasing decisions against these buffers.
If you have two identical electric cars for the same price, one with a range of 350 miles and one with a range of 280 miles, which one would you buy?
If you have two identical phones, one with a 4300 mAh rated battery and another with a 3400 mAh battery, which one would you buy?
If you have two equally priced SSDs, one with 500GB capacity and one with 480GB, which one would you buy?
To enterprise customers the sales rep will explain "look, this device has a bit less space, but the write endurance number quoted here is much better, over 5 years and 5000 drives this will lower your TCO by X". In the consumer space you build your entire brand around one price-reliability tradeoff and stick to it, and usually the cheaper one with the bigger headline stat sells the most.
