The biggest difference between consumer and enterprise SSDs is that an enterprise SSD should provide the guarantee that when it responds to the host system confirming that data has been safely stored, it actually is. That is to say, that if power is suddenly removed from a system all data that the operating system believes was committed to disk will be safely stored in flash. Furthermore, it should also be expected that in order to accelerate writes but maintain the data safety condition, the SSDs will contain super capacitors to provide just enough power to flush the SSDs RAM buffer to flash in the event of a power loss condition.

Enterprise SSDs are normally provided in a number of different flavors to provide a wide cost per GB options balanced against write endurance.
