The best USB drives will make your most important files easily portable. You’ll be able to quickly move data from one computer to another, or to other devices, with little fuss. You just plug in the drive and start dragging-and-dropping files. 

With storage prices falling and USB technology improving, it’s no surprise that USB drives continue to be a popular solution for carrying around massive amounts of data. For just a few bucks, you can probably carry in your pocket all of the personal files and folders stored on your laptop or desktop PC. 

But buying a USB drive isn’t as simple as you might think. There are different types of connections, including USB 2.0, USB 3.0 and USB 3.1. (Newer is better.) You’ll also want to know about the drives’ read and write speeds to get a sense of data-transfer performance.

What are the best USB drives?

In a world where USB drives are easy to come by, finding one that gets the job done and delivers significant value isn’t the simplest of tasks. 

In our evaluation of a variety of devices, we found Samsung’s Fit Plus (MUF-128AB) to be the best USB drive. It offers an outstanding mix of features and affordability, with USB 3.1 support, read speeds up to 300 MB/s and a design that’s so compact that you can leave it in your laptop without worrying about damage.

We also found the SanDisk Cruzer CZ36 to be a great choice, as you get secure 128-bit AES encryption for a very low price. You just have to be willing to live with USB 2.0 compatibility. If you want zippy read/write speeds, you’ll be hard-pressed to find many devices better than Kingston’s Digital DataTraveler G4.

If you’re in the market for one of the very best USB drives available, and you’re just fine spending some cash to get it, check out the SanDisk iXpand flash drive. The device features 128GB of storage, though you can configure the iXpand to have up to 256GB of space. It has a metal finish to improve its durability, and thanks to its USB 3.0 connectivity, the device will deliver fast data transfers.

The iXpand flash drive’s most important feature is its Lightning connector, which lets you connect to an iPhone or iPad and transfer data to and from that device. Considering how difficult it can be to transfer data from those devices without Apple’s help, that feature alone could be a major selling point for the iXpand. But to get all that, be ready to shell out: The SanDisk iXpand flash drive is on the expensive side.

How to choose the best USB drive for you

When buying USB drives, you’ll want to focus first on storage. If you have a large number of files, videos, or songs you want to carry around with you on a device, getting a USB drive with at least 64GB is critical, and many go up to 256GB or more. If you’re more concerned about getting a cheap USB drive for carrying fewer files, you can probably get by with 16GB or 32B.

Aside from that, you’ll want to consider other critical features, like read/write speeds. The faster the speeds, the more data you can write to the drive and access when you’re trying to see files. That’s why we would look for USB 3.1 support or (at the least) USB 3.0 support if you care about performance.

Another factor to consider is design. USB drives aren’t the sexiest of devices, but they come in a variety of shapes and sizes. In terms of durability, look for USB drives that have shock-proof designs, waterproof-designs, and other features that limit chances of your drive being damaged. Last but least, check the warranty on that USB drive; a lifetime warranty is preferred but 5 years is a decent fallback option.
