Backing up data from a computer or mobile device has never been easier. You can transmit data to the cloud, save it to an external hard drive, or transfer your data easily and quickly to a flash drive. Now, we’re not going to judge you on how often you’re backing up your data. (We’ll just assume you’re like most people and it’s probably not often enough.) Instead, we want to help you successfully back up your data by figuring out how to pick the best flash drive. The great thing about flash drives is that they’re easy to use. You can also carry important files with you wherever you go and protect your files with encryption on a flash drive, which makes these devices very versatile.

We seek to give our readers the information they need to make a smart purchase. Additionally, we never accept free samples from manufacturers, which means you can feel comfortable that our selections and product reviews remain free of bias.

Apple smart products don’t come with USB ports, so you will need a backwards compatible drive that can also plug into lightning devices. This thumbdrive from SanDisk is designed for ease of use with iPhones and iPads, thanks to a curbed plastic connector that fits behind the back of the screen. It has high-speed USB 3.0 transfer speeds and can hold over 7,200 photos or 8,000 songs. It has automatic photo backup and contact transfer to help free up space on your devices without having to deal with the slow upload speeds.

Our tester highly recommended this flash drive for iOS mobile users: “The iXpand is a great resource for backing up media files and for expanding storage, as well as transferring files to a PC.” He added, “The Drive App is easy to navigate and copy files with, as well as operate the camera and play music and video files.” On the other hand, our reviewer reported, “The 30 MB/s write speed on PC is far from horrible but definitely slow for the asking price, and we calculated only about a 12 MB/s when connected to an iOS device.” He ultimately concluded, “A slightly cheaper price would make it the surefire winner in the Lightning connector category.”

Buoyed by its rocket-like speeds, the Extreme Go lives up to its name by transferring a 4K movie in less than 40 seconds — that's nearly 35 times the speed of a USB 2.0 drive and thanks to USB 3.1 hardware. Beyond its fast operation, the Sandisk looks as good as it performs with a sleek and slim package that's 2.79 x 0.84 x 0.45 inches in size and weighs only 4.8 ounces. The retractable connector makes it easy to store when not in use and it is backward compatible with any USB 3.0 or USB 2.0 port. Tucked inside its diminutive profile is a choice of 64GB or 128GB of storage capacity and it comes complete with data storage recovery in the event of an accidental file deletion. 


This depends on the programs. Most programs will situate their contents in multiple locations, so if it's on your computer, you'll need to know where all of a program is stored. It can be easier to download the program from scratch again as it brings in all of the needed content for you. If you are trying to transfer from a computer, at the very least be sure to capture the EXE, Application and Java files; however, there are usually many other files too. Also, the programs will differ between operating systems (for example, EXE is Windows, while .app is Mac). End answer: it can be done but it's easier if you can download the program afresh.
There's a lot to choose from when it comes to buying a flash drive. The most important thing to consider is size. The whole point of a USB drive is to store lots of data in a small space, so think about what kinds of files you'll want to house on your flash drive. Movies and music take quite a bit of space, so if you're carrying your whole entertainment library with you, you'll want a big thumb drive – at least 16GB. Books and other text-based documents require relatively little storage space, so people like students and working professionals using Microsoft Office would be happy transferring Word documents or Excel files with as little as 1GB of space. On the other hand, if you are using photo or music editing software, you'll want a USB flash drive with lots of storage capacity to transfer graphic and music files.
