USB storage devices, also known as USB drives, USB sticks, or flash drives, are small data storage devices that plug into the USB port on your computer. They provide portable, removable data storage that allows you to easily transfer files between devices. USB drives come in a variety of storage capacities and are inexpensive, durable, and easy to use.
What is a USB Storage Device?
A USB storage device, sometimes called a USB drive, USB stick, or flash drive, is a small peripheral that plugs into the USB port on your computer to provide additional storage space. It allows you to store and transfer documents, photos, music, videos, and other files between devices. The “USB” name comes from the Universal Serial Bus interface that allows the device to connect to your computer.
USB drives are often small, lightweight, and portable, about the size of a large thumb drive. They connect with a standard USB plug that goes into any available USB port on a computer or other device. USB drives contain flash memory, a type of digital storage that does not require a battery or external power. Once plugged in, the USB drive appears on your computer as an external storage device.
USB storage offers removable data storage that can supplement limited internal storage on a computer. You can store, transfer, and share files by simply plugging the drive into any device with a USB port. This makes moving files between home and work computers or sharing large files fast and convenient.

The basic steps are the same for Chromebooks, Linux PCs, and other devices with a USB port. The drive acts as external storage that you can access through your computer’s file manager system.
Managing Files on a USB Drive
Handling the documents, media, and other data stored on your USB drive is simple to do. You can organize, edit, share, and backup files using familiar features and functions:
- Create folders on the USB drive to categorize and organize your files.
- Select and copy files and folders you want to transfer onto the device.
- Safely eject the USB drive before removing it from your computer.
- Access and edit documents or other files using compatible apps.
- Share files by emailing them directly from the USB drive.
- Setup automatic file syncing and backups to the removable drive.
- Password protect and encrypt confidential data stored on the device.
Storing sensitive business files or financial data? Enable built-in security so no one can access them without a password or encryption key if the USB drive gets lost.
Sharing Files from a USB Drive
One of the big benefits of a USB storage device is being able to easily share files with others. You don’t need an internet connection – just physically hand them the USB drive. Some ways you can share files from a USB drive:
- Hand the USB drive directly to someone else to access the files.
- Copy/paste or drag and drop files to another computer.
- Allow network access to a shared USB drive connected to a PC.
- Share a USB drive with co-workers by passing it around the office.
- Present files directly from a USB drive during a meeting or conference.
- Mail the USB drive to safely send large files that are too big for email.
Granting access to an entire USB drive gives people complete flexibility on accessing, copying, and sharing any of the saved files as needed.
Sharing Large Files
USB drives excel at sharing large files that are too big to attach to an email. Even with file compression, email services typically limit attachments to 25MB or less – a USB drive can store gigabytes.
To share large files up to 4GB or more:
- Copy the large files you want to share to the USB drive.
- Physically deliver the USB drive to the recipient.
- They can then copy the files directly to their own computer.
Using a USB drive avoids slow uploading/downloading or potential file corruption. The recipient also gets their own copy of the files for access whenever needed.
| File Size | Email Transfer | USB Drive Transfer |
|---|---|---|
| 10MB | Slow but doable | Very fast |
| 100MB | Not recommended | Very fast |
| 2GB | Impossible | Very fast |
| 8GB | Impossible | Very fast |
As the table shows, email transfer slows down even at 10MB and is not feasible about 100MB. A USB drive maintains fast transfer speeds regardless of file size.
Backing Up Files to a USB Drive
One of the handiest uses for a USB storage device is to backup important files for protection from system crashes or hardware failures. USB drives are ideal for full or incremental backups.
How to Backup to a USB Drive
Backing up files involves copying them from your computer’s internal drive to the external USB drive. You can manually select files or set up an automated system backup.
- Manual file copy – Drag and drop files to the USB drive or use copy/paste.
- Backup software – Use built-in tools like Windows Backup or third-party software.
- Sync utility – Install a file sync utility that automates backups to the USB drive.
Software and utilities can schedule regular, automated backups in the background and sync file changes. This ensures the USB drive always has an up-to-date copy as your backup.
What to Backup to a USB Drive
Determining which files to backup depends on your needs. Recommended items to include are:
- Personal documents
- Digital photos and media
- Business presentations
- Financial records
- Settings and app configuration files
- Program installers and license codes
You may want to do a full system backup to save an entire drive image if completely restoring your system. For file-level backups, prioritize irreplaceable data and large downloads or media.
Benefits of USB Drive Backup
Having an external backup of your system and files provides many advantages:
- Insurance against data loss – Recover deleted or damaged files from the USB drive.
- Portability – Carry backed up files anywhere for access on multiple devices.
- Isolation – USB drive backups are detached from your main computer system.
- Convenience – Setup scheduled or real-time file syncing to the USB backup.
- Peace of mind – Know you have copies of priceless photos and important documents.
With storage so cheap, there’s little excuse not to maintain both a local and a portable USB drive backup of your most critical computer files.
Securing a USB Storage Device
While convenient for transferring and sharing files, a USB drive’s portability also makes it prone to loss or theft. If storing sensitive personal or work documents, it’s essential to secure the device.
Locking the Drive
One quick way to protect the data is to lock or password-protect the USB drive. This renders files inaccessible without entering a password or encryption key.
Most name brand USB drives come with built-in security software to create a password lock. For example, a SanDisk USB drive can be locked using SanDisk SecureAccess software. There are also third-party utilities that add encryption security.
Other Precautions
Some other precautions when using a USB drive:
- Manually eject/unmount the drive before removing it.
- Always keep USB drives in a secure place when not in use.
