   • Storing files locally
     • Hard drives - built in magnetic storage devices containing high amounts of storage
       • secondary storage
         • Solid state- things like sd cards and usb sticks. Very small and compact which leads to not having lots of storage space but are more durable than other secondary storage devices
         • Optical- DVD's and discs. Can hold alot of files , lots more than solid state. Cheap and not durable
         • Magnetic- Holds the most storage and is very durable but very , very expensive
