CD's are plastic and tend to be back-up storage, or media-based, as they are usually only capable of holding 700 mb's of storage. A hard disk is made of a metal alloy, has much faster reading/writing speeds (depending on the age of the drive, and whether it is IDE or SATA/SATA2/SATA3) and is capable of holding much larger quantities. Some exist out there that can hold 2TB of data. That's roughly 2,000GB, or 2,000,000MB. CD's are also easily removable, simply hit an eject button. Hard Drives require a full shut down.
