Hard Disks Part 2

A head crash occurs when a read/write head touches the surface of a platter
Always keep a backup of your hard disk
Disk cache, sometimes called a buffer, consists of a memory chip(s) on a hard disk that stores frequently accessed data, instructions, and information
The larger the disk cache, the faster the hard disk

RAID (redundant array of independent disks) is a group of two or more integrated hard disks
An external hard disk is a separate freestanding storage device that connects with a cable to a USB port or other port on a computer or mobile device


....... getting a bit hard isn't it?
