SSD AND HARD DRIVE

An SSD (solid-state drive or solid-state disk) is a non-volatile storage device that stores persistent data on solid-state flash memory. SSDs actually aren't hard drives at all in the traditional sense of the term, as there are no moving parts involved.

STORAGE

With all our photos, apps and games, if there's one thing we never seem to have enough of on our smartphones, it's space! However, a lot of devices get around this issue by allowing the use of memory cards, which these days you can get in a range of sizes.

For mobile phones and tablets, the type of memory card you'll need is a microSD. These types of cards are barely bigger than your fingernail, but can store enormous amounts of data.
