Jump drive

16GB SanDisk Cruzer Micro USB Flash Drive1. Alternatively referred to as a USB flash drive, data stick, pen drive, memory unit, key chain drive and thumb drive, a jump drive is a portable storage device. It is often the size of a human thumb (hence the name), and it connects to a computer via a USB port. Flash drives are an easy way to store and transfer information. They are available in sizes ranging from 2 GB to 1 TB.

Unlike a standard hard drive, the flash drive has no movable parts; it contains only an integrated circuit memory chip that is used to store data. Flash drives usually have plastic or aluminum casings surrounding the memory chip and a USB connector for use with most modern computers.

How do I use a flash drive?

A flash drive can be utilized like any drive on your computer. Start by inserting the flash drive into a front or back USB port or a USB hub. Once connected, in Windows open My Computer or File Explorer and you should see the drive labeled as "Removable Disk," "Flash drive," or as the manufacturer's name. Once the appropriate drive letter for your device has been determined, you can copy any file you want, and then paste it onto the flash drive. You can also drag-and-drop files onto the flash drive.

Tip: If you're having trouble locating the drive letter of your flash drive, take a look at the next section.

What drive letter is my flash drive?

When connecting a flash drive to a computer on Microsoft Windows, it becomes the first available drive letter after those already in use. For example, your hard drive is C: and your disc drive is D:, then your flash drive would likely be the E: drive. An exception to this rule would be if you have more than one hard drive. If you are still unsure, open File Explorer and watch for a new drive to appear after you insert the thumb drive.

What is the difference between a jump drive and a flash drive?

A jump drive and a flash drive are one and the same, but with different names. The confusion seems to arise in the difference between a flash drive, which is a device (detailed above) and flash memory, which is a non-volatile storage medium. Flash memory is used in many devices, including flash drives, solid-state drives, and memory cards.

How are USB flash drives used?

The USB flash drive is most often used to store and transfer files between computers. For example, you could write a report on a school computer, copy the file to a USB flash drive and then connect it to your home computer to continue working on that same file. USB flash drives are also a great and easy way to backup your important files. For example, you could copy all of your pictures, documents, music, or other files to a flash drive and store that flash drive somewhere safe in case something were to happen to your computer.

Tip: Like all past storage media, flash drives are now being replaced by cloud storage. If you are looking for faster methods of transferring data, you can use cloud storage as an alternative method.

What did people use before flash drives to store data?

Before the popularity of flash drives, most people used recordable CDs and DVDs to store and backup data.

How big of flash drive should I get?

Today, even a 16GB flash drive is not that much money, and we typically recommend buying as much as you can afford. However, if you are only planning on storing a few document files or not that many files on the drive, you can save yourself some money by buying a smaller drive.
