Whether you call them thumb drives, USB sticks, or by any of their countless other monikers, the best USB flash drives remain one of the easiest ways to move your data. One of the most crucial considerations when choosing the right drive is figuring out how much capacity you need. If you're just shifting smaller files, like photos or documents, a 16-32GB drive should provide all the space you need. On the other end of the spectrum, for moving stuff like larger video files or full game installations, you're going to need a much higher capacity option, something in the 256GB range.

Speed is also a consideration, particularly on the higher end of the storage range. The fastest drives will feature USB-C connectivity, which support up to twice the transfer speed of USB 3 drives (topping out at 10Gbps), though speed is also influenced by the type of flash memory and controller a drive uses. Regardless of which model you choose, you'll want one of the best desktop PCs to ensure that you've got the proper ports available to take full advantage of a high-end USB flash drive.

Best Overall: SanDisk Extreme PRO 128 GB Drive

The SanDisk PRO gives you blistering speeds, offering 420 MB/s on the reading front and 380 MB/s on the writing end, which is 3–4x faster than what a standard USB 3.0 drive will offer. The sleek, aluminum casing is both super durable and very eye-catching, so you can bring it with you to your business meetings and look professional as well.

The onboard AES, 128-bit file encryption gives you top-of-the-line security for your sensitive files. That USB 3.1 connection is also backward compatible with USB 2.0, so you won’t hit any snags with an older computer. SanDisk is so confident in the functionality of this little drive, that they’ve even backed it with a full lifetime warranty in case any issues befall it. Finally, there’s a file backup system you can download called RescuePRO that will let you recover lost files if needed.

Best Budget: Kingston DataTraveler SE9 G2 Flash Drive

You can get USB 3.0 speed in a compact and durable metal USB drive from Kingston for ridiculously cheap. The DataTraveler comes in a variety of capacities and regardless of which you choose, you're getting a huge discount per GB compared to nearly any other competing USB flash drive.

It sports a capless design with a sturdy keyring, perfect for travel or as a part of your everyday carry. The design can even be customized to add your logo or company name. The USB 3.0 standard means read speeds top 100 Mb/s; not the absolute fastest drive available but still very speedy, especially if you're moving smaller files. With a five-year warranty, a great design, and a value price, this small drive makes a perfect addition to your keyring. 

Best for Apple Products: SanDisk iXpand 128GB Flash Drive

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.

Best for Ultrabooks: Samsung 32GB USB 3.0 Flash Drive Fit

With their paper-slim profiles, Ultrabooks and tablets are barely thick enough for a USB port. That's why some of the bulkier drives on this list are not ideal for those devices. Meanwhile, Samsung’s Fit drives are slim and compact, about the size of your thumb nail. This unobtrusive storage is constructed with a metal casing that is resistant to the elements and NAND flash technology. With USB 3.0 tech you can expect fast read speeds, while the price is easy to stomach. Just make sure to attach it to a lanyard, so you don't lose it.

Best for Macbooks: Silicon Power C80 64GB Flash Drive

Macbooks require a USB Type-C device, which is where this swivel dual flash drive from Silicon Power comes in handy. It features a dual interface with USB Type-C and USB Type-A 3.0 ports on opposite ends of a compact device. The 360-degree swivel cap protects whichever connector is not in use and attaches easily to keychains. The C80 doesn’t require any special drivers or software to work; just plug it into the port and it is ready to go. But it has an optional file management app, which is a free and simple automatic file categorization that puts your work in the appropriate folders. Expect fast read and write speeds and 64 GB of storage to hold all your photos and files.

Best for Security: Kingston Data Traveler Vault

High-security flash drives aren’t exactly a new concept. For as long as companies have been transferring confidential info via USB drives, there’s been a concern of keeping that info confidential. While you might be swayed by flashy gimmicks like fingerprint sensors and password keypads, these end up being too expensive and not overly powerful (with a few exceptions of course). But that’s why our security pick goes to the Kingston Data Traveler Vault.

This USB 3.0 drive offers what the company is calling business-grade security with 256-bit AES hardware-based encryption. You can also choose a stepped up “managed” version that offers a more complete set of management tools using SafeConsole as support. Finally, there’s an anti-virus version that loads in ESET antivirus software out of the box to avoid trojan horses and other hacker tracking programs. All of the models are TAA-compliant, so this drive won’t be in breach of government regulations, and that USB 3.0 means that you’ll have nearly the fastest transfer speeds possible. You can pick it up in sizes ranging from 4GB to 64GB.

Most Rugged: Corsair Flash Survivor Stealth 64-bit USB 3.0 Flash Drive

If you are taking your data to the extreme ends of the Earth and need to go a step above and beyond to keep it safe, the rugged Corsair Flash Survivor Stealth 64-bit is the drive for you. Constructed with aircraft-grade aluminum housing and outfitted with a molded shock damping collar, this drive is meant to survive anything you can throw at it. It can even be submerged in up to 200 meters of water because of the EPDM (ethylene propylene diene monomer rubber) waterproof seal. With speeds at around 85 MB/s, this isn’t the fastest drive around, but its ruggedness is unparalleled.

Best Capacity: PNY Turbo 256GB

Nothing fancy here, but when you need a quarter of a terabyte in a pinch, the PNY turbo has got your back. Boasting a capacity of up to 256GB, this flash drive has got it where it counts, making storage of all but the most colossal files just a drag-and-drop away. Equipped with a collapsable USB-A port, the PNY Turbo utilizes USB 3.0 architecture to supply the best possible transfer speeds currently available over a USB-A connection.

While it doesn't offer features like wireless connectivity, or data encryption, the PNY Turbo is still great for offloading a glut of files that might otherwise be taking up valuable real estate on your machine. It may not be the cheapest flash-drive available, but the price per GB still provides excellent value.

Final Verdict

A perfect balance of capacity and performance at a very reasonable price point, Sandisk's Extreme Pro takes our top spot. It's a drive that takes full advantage of advancements in solid-state storage to deliver amazing transfer rates. For an absolutely bargain-basement alternative that still provides plenty of storage, Kingston's Data Traveler which comes in a number of different sizes that are all very competitively priced.

What to Look for in a USB Flash Drive

Speed - If it’s speed you seek, go for a flash drive that has USB 3.0, 3.1, or 3.2 technology, which is up to ten times faster than the USB 2.0 standard.

Security - Often times the data you’re transferring is highly sensitive, which means your basic flash drive won’t cut it. Spring for a flash drive with a numerical touchpad that allows you to password protect your files. Or better yet, snag one that requires your fingerprint.

Capacity - More so than any other feature, capacity will drive the price of a flash drive up the most. So before you make a purchase, consider how much you’re willing to spend on a flash drive and weigh that against how much capacity you’ll likely need, and what kinds of files you're looking to shuffle around.
