    I need an external hard drive for taking regular backups of all of my data.
    When i searched the internet I got two options:
    1. Porable HDD [high cost, slower speed but don't need external power]
    2. Desktop HDD [low cost, higher speed but need external power]

    I want to know that...
    1. Which hard disk's live longer? Porable or Desktop.
    2. I heared that pulling off USB cable of Portable HDD may cause data lose because it also supplies power to hdd.
    What will happpen if Power goes off from Desktop HDD? Will my data/Hard disk remain protected?
    3. Level of safety of data on moving or shaking on both Desktop and Portable HDD.
    4. Can we install os and boot from portable and desktop external hdd?

    Unless you really need to go portable with a Laptop .. I'd not use a USB powered External.
    You cannot boot from a USB External .. But there's another option if you're capable of physically changing HDDs ..

    Get a good external Enclosure (with a fan for cooling) .. Install a good HDD ... with a 5 year warranty
    and make the HDD in the enclosure a bootable backup .. where you could swap HDDs if/when needed ..
