Carry Everything You Need on a Tiny USB Stick

USB flash drives nowadays are inexpensive, common storage devices; you can even regularly find them given away for free as promotional items. Even though they're cheap and ubiquitous, don't overlook the power of these little storage devices.

Use a USB Flash Drive to Keep Essential Files Always Available

USB flash drives hold several gigabytes of data, which is enough to make sure you always have in your pocket or on your keychain stuff like your latest projects files, Outlook files, photos of your house and equipment for insurance purposes, medical records, contact lists, and other essential information you would need with you in case of emergency or just for access on the go. If you sometimes have to work in different offices or travel a lot, USB flash drives are great tools for accessing your work files wherever you go.

Although most people have stopped using flash drives for data storage, opting instead for cloud services like Microsoft OneDrive or Google Drive, a USB drive makes a handy backup for situations like public presentations where you cannot access your cloud drive from someone else's computer.

Before you store any sensitive information on your USB flash drive, however, make encrypt the drive so the data on it is protected in case it ever gets lost (a likely scenario, with an estimated 4,500 USB sticks lost or forgotten every year in the UK alone, left in places like dry cleaners and taxis).

Portable Apps

Most popular programs offer portable versions that can be installed and run entirely off of USB flash drives or other portable hardware without changing the computer's hard drive. Another benefit of using portable apps on USB sticks is that when you remove the USB drive, no personal data is left behind. There's a portable version of Firefox, OpenOffice portable, and many others.

If your USB flash drive is a "U3 smart drive" (many SanDisk drives are U3 capable because SanDisk holds the rights to the U3 platform), choose from thousands of U3 "smart applications" to install and run from the U3 Launchpad. Many U3 drives ship with portable apps like Firefox, RoboForm2Go, Evernote, and McAfee Antivirus.

The free, open-source PortableApps suite includes an integrated menu and backup utility as well as a Firefox browser, Thunderbird email client, Sunbird calendar/task, Pidgin instant messaging, Sumatra PDF reader, KeePass password manager, OpenOffice, CoolPlayer+ audio player, and some games.

Download portable apps directly from the software providers' websites or from directories like USB Pen Drive Apps.

Use a USB Flash Drive to Troubleshoot and Repair Computer Problems

Utilities for troubleshooting computer problems and running diagnostics run directly from a USB flash drive; they offer a tool to fix boot-up errors as well. AVG, for example, ships a USB-optimized antivirus application that runs a virus scan on a troubled PC from the USB drive.

Your USB flash drive repair kit should include utilities like the these:

Use a USB Flash Drive to Make Windows Run Faster With Windows ReadyBoost

Windows Vista and Windows 7 users can use USB flash drives to improve system performance by using the USB drive or an SD card as an additional memory cache. When you connect a compatible removable storage device to your computer, ​Windows ReadyBoost automatically launches and asks if you want to use the device to speed up performance with Windows ReadyBoost. (If you change your mind, you can later ​​disable Windows ReadyBoost for the flash drive.)

The amount of space Microsoft recommends setting aside on your USB flash drive for ReadyBoost is one to three times the amount of memory on your computer; so if you have 1GB of RAM on your computer, use 1GB to 3GB on the flash drive for ReadyBoost.

Not all USB flash drives are compatible with ReadyBoost. The drive must be at least 256MB and drives offer poor write and random-read performance can fail the compatibility test. If you have a compatible device, though, using ReadyBoost can make a significant difference in how fast Windows starts and loads applications.

Use a USB Flash Drive to Run a Separate Operating System

Run a separate operating system from your USB flash drive so you won't have to modify your computer's hard drive. If you're curious about Linux, for example, buy a USB flash drive with Damn Small Linux already embedded in the USB pen or install your favorite Linux OS from the USB drive using Pen Drive Linux.

It's even possible to boot Windows XP from a USB flash drive, which can be useful if your PC is unbootable and you need to get back into it to troubleshoot and repair.
