    I wonder how long a flash drive will survive. Shouldn’t the nand gates release its electron that it holded for 2 to 12 years?

    Is an SSD the same or similar to a flash drive?

      In terms of gates - kind of. They’re relatively similar at this point.

      The major difference (to my understanding) is the difference between a flash drive, SD card, and SSD is the controller and cache.

      Flash drives and SD cards have no cache and no fancy controller. SSDs have a controller that is aware of its memory cells and can load balance them, cache data on differently configured cells (or RAM, depending on the hardware), and perform maintenance on cells the OS declares to be empty.
