    2. 2. Topics<br />FDD<br />HDD<br />Optical drives<br />Removable storage<br />
    3. 3. FDD<br />What is FDD?<br />Floppy Disk Drives<br />Used to read & write info to & from floppy disk.<br />What are the advantages?<br />Portability<br />What are the disadvantages?<br />Limited storage capacity<br />
    4. 4. Types of Floppy Formats<br />There are five types:<br />DD = Double Density<br />HD = High Density<br />ED = Extended Density<br />
    5. 5. HDD<br />What is HDD?<br />Hard Disk Drive<br /> What is it used for?<br />Permanent and quick storage<br />Contains three critical components<br />
    6. 6. Critical Components<br />There are three critical components of a HD<br />Controller<br />Hard Disk<br />Host Adapter<br />
    7. 7. Controller<br />Controls the drive<br />Controller chip controls how the drive operates, it sends signals to various motors in the disk and receives signals from the sensors in the drive<br />Hard disk<br />Physical storage medium<br />Store information on platters<br />Host adapter<br />The translator<br />Converts signals form the hard drive and controller to signals the computer can understand.<br />
    8. 8. Types of Hard Drives<br />Magnetic<br />Solid-State Drives<br />Moving parts<br />Less reliable<br />Higher storage capacity<br />No moving parts<br />USB technology<br />Lower life<br />More reliable<br />Lower storage capacity<br />

    15. 15. Removable Storage<br />Tape Backup Devices<br />Solid State<br />External CD-RW and hard drive<br />Hot swappable devices and non-hot swappable devices<br />
    16. 16. Tape Backup Devices<br />An older form of removable storage<br />Can be internally or externally installed<br />Holds more data than any other medium<br />
    17. 17. Solid State<br />Thumb drive<br />SD cards<br />
    18. 18. Thumb drive<br />Uses the USB interface which takes advantage of the plug and play feature.<br />Replacement for the floppy disk, Zip, and Jazz<br />
    19. 19. SD cards<br />Stands for Secure Digital<br />One of the smallest forms of data storage<br />Used in many types of current technologies<br />miniSD<br />microSD<br />
    20. 20. External CD-RW and Hard Drive<br />Use the USB<br />Portable<br />Very useful for some laptops, desktops and all netbooks<br />
    21. 21. Hot swappable devices and non-hot swappable devices<br />Hot swappable devices<br />Devices can be inserted and removed when the system is powered on.<br />Non-hot swappable devices<br />Warm-swappable <br />Thumb drives and external drives<br />You need use the Safely Remove Hardware utility<br />Cold-swappable<br />Need to have your power shut off before you insert or remove<br />Keyboard or mouse<br />
