Everyone who uses a computer has several of these handy pocket size storage devices lying around. For most of us, it’s just a neat little gadget to store photos, documents, and files.

How many of you realize that these drives can be used for other purposes than just storing data and files? Before I get into these other features, I just want to touch on the subject of USB 2.0 vs 3.0 drives.

Simply, USB 3.0 is much faster, up to 10x faster.
Check this quick reference chart:

So what other uses do USB Flash Drives provide besides storing information?

  • Run Antivirus software to remove unwanted malware from any computer
  • Execute maintenance applications to troubleshoot or fix slow operating computers
  • Run another operating such as Linux off your USB Flash Drive
  • Execute portable apps such as Chrome, Firefox, Open Office, Evernote and more from your Flash Drive.
  • Tired of using passwords to unlock your laptop, try using
    a physical key such as: Predator (Win), Rohos (Win & Mac)
    or USB Lock (Mac)
  • Keep important files, contact lists, medical information,
    projects, and special photos always on hand.
  • Store MP3 files to listen on other devices that have a USB port
  • Promote your business: Print your logo and store your
    business information on the drive, give away free

I am sure there are lots of other uses I didn’t mention.
Feel free to share them with us.
