NAND

Example of a NAND chip.

This refers to the NAND flash chip used in the Apple TV, iPad, iPhone, iPod touch, and Template:Wp (Late 2010). This is where all the storage capacity comes from. The capacity can range from as little as 4GB to as many as 128GB. in iOS, it is partitioned into two: the system partition and the user partition. The system partition contains the iOS operating system and the native Apple applications, and is mounted as read-only. The user partition contains all user data, including installed applications, music, and movies, and is mounted as read/write. A bare-bones jailbreak modifies the file "/etc/fstab" and enables read and write on both partitions.
