Flash Storage vs SSD
So, from what I understand, in principle, the Flash Storage have the same software-hardware of the SSD Storage (Solid State Disk).
Both of them do not use mechanical components, both of them are fast, both of them are small, etc.
But specifically, I read that there are still differences between Flash Storage vs SSD Storage.
The Flash Storage are smaller than SSD Storage, are even faster, for example, are essential to the macbook pro and air that use the retina technology, and thanks to them that only some apps work as Power Nap, etc..
Is this true? what other differences are between Flash Storage and SSD storage?
thanks
