Why are SD cards smaller than SSDs?

2 – SD cards don’t need the extra circuitry that SSDs need in order to communicate with the devices they’re being used with. Therefore, an SD card only has to be large enough to hold a flash memory chip or two plus a tiny controller chip. Those, in a nutshell, are the reasons why SSDs are so much larger than SD cards.

Among these technologies, the most important is the “wear-leveling” algorithms that effectively make sure all the drive’s memory chips are used up, cell by cell, before the first cell can be written to again. This also means that SSDs of larger capacities generally have longer life spans than do smaller ones.
