- - - - HARD DISKS
        
        FUNCTION: Storage device that contains one or more inflexible, circular platters that use magnetic particles to store data,instructions and information.
        
        CHARACTERISTICS: -High capacity storage -Components enclosed in airtight,sealed case for protection.
        
        TYPES OF HARD DISKS
        
        Internal Hard Disks
        
        An internal hard disk can be mounted inside a desktop or laptop
        
        External Hard Disks
        
        An external hard disk is a separate freestanding storage device that connects with a cable to a USB part or other part on a computer or mobile device.
      - Solid State Storage
        
        FUNCTION: A storage device that used flash memory to store data ,instructions and information.
        
        CHARACTERISTICS: -SSD contain no moving part. -Current SSDs storage capacity up to 8 TB
        
        BENEFITS: -Faster access time -Faster transfer rates. -More durable and shock resistant (no moving part). -Generate less heat and consume less power.
        
        DRAWBACKS: -High failure rate. -Cost is much higher.
      - Flash Memory Storage
        
        -Flash memory storage is a storage media that used solid-state chip that maintains stored data without any external power source.
        
        -Commonly used in portable electronics and removable storage devices.
        
        -More durable and shock resistant than other types of secondary storage because it contains no moving part.
