- Much more convenient, will work with almost any computer as long as there is a flash drive
- Great storage space
- It's small size is convenient for carrying, and takes little space
- One can purchase a USB that more relfects them through its colors and design
Disadvantages:
- It's small size also means it can be lost easily and/or forgotten
- Its life span can be short, about several hundred thousand cycles
- As the device ages the speed of writing process gradually slows
- Only a few USB flash drives are equipped with a write-protect mechanism, meaning those that don't have the protection could be contaminated by what ever virus the computer it was connected to has
- If inappropriately removed from the USB drive without being ejected, it become damaged or lose the data saved to it
