Despite the increasing use of online approaches such as cloud storage, instant messaging, and email to share digital files, there’s still a place for old-school methods like USB flash drives.

They’ve long been a reliable, compact way of sharing and storing information while you’re on the go, especially for large files or when internet access isn’t available.

When buying a USB flash drive, consider what your primary use will be and who is going to use it. If you’re a business traveler, for instance, you might want to go with a more security-minded USB flash drive.

If you give your equipment a hard time, a metal or waterproof version is worth considering, while videographers and others who need to store and move large files around should look for drives with high transfer speeds.

What to Look for in a USB Flash Drive

Speed & Compatibility

Compatibility with the devices you plan to use is obviously a key factor when buying a flash drive, so it’s worth checking the specifications of both the drive and the USB ports on your computer to make sure the read and write speeds suit your level of patience.

Whether you use Windows, Mac, or Linux also makes a difference, not so much for which drive to buy, but how you choose to format it. Sticking with the same operating system won’t cause any problems, but switching between file systems can result in read-only or compatibility issues when switching between computers.

If you’re hoping to use the drive with your phone, or tablet, look for an Android drive with On-the-Go (OTG) support.

Capacity

USB flash drive storage ranges from about 32GB to 1TB, and typically goes up in price as the capacity gets larger. Some people need more storage than others: video files, for instance, need more space than photos or standard workplace documents.

When choosing which drive to buy, consider how much data storage you might need. It’s worth buying a bit extra if the price difference isn’t too high, but the highest-capacity models often cost a lot more. It may make more sense to buy two 500GB drives, for example, than a single 1TB model.

Style

The style of the USB flash drive is also something to consider. Do you want a smaller, more compact device? If so, you might be sacrificing capacity or transfer speed for size. Like many other things in life, metal versions often cost more (sometimes, a lot more) than their plastic counterparts.

Durability

While flash drives have gotten faster, smaller, and higher-capacity over the years, their durability hasn’t always kept pace. These are sensitive electronic items that can get damaged when they’re knocked around.

Most flash drives on the market last a few years on average, but exposure to heat, impact, and moisture can substantially lower their lifespan. As a result, you may want to look for water resistance in addition to a durable housing.

Security

Device security is (or at least, should be) a concern, especially if you’re storing sensitive information on it. If keeping your files safe from anyone who gets their hands on your flash drive is important, look out for a model that encrypts and protects your data with a fingerprint reader, pinpad, or similar.

Taking all these factors into account, here are our picks for the best USB flash drives in 2021.

Best USB C Flash Drive on a Budget: MOSDART Type C Thumb Drive

Best USB-C Flash Drive: MOSDART Type C Thumb Drive
  • Capacity: 64-256GB
  • Compatibility: USB C, USB-A 3.0
  • Speed: 75-85Mbps read, 20-30Mbps write
  • Extra features: Lanyard

USB C has become increasingly common on phones, tablets, and computers in recent years, and for good reason. It lets you charge at high speed, copy files, and connect accessories all from the same socket, with a plug that’s reversible and easy to insert.

USB C flash drives, however, have been quite slow to appear, which seems odd: offering faster transfer speeds than older models and with that handy reversible plug that means you’re not endlessly fumbling around trying to connect it, they should be more popular than they are.

The MOSDART Type C Thumb Drive doesn’t need any additional apps, offers up to 85Mbps read speed, and has two connectors: USB C for newer devices, and USB-A for older machines.

The plug on this flash drive is long enough to work with most phone cases and includes a lanyard for convenience of carrying. It’s available in capacities from 64-256GB.

It’s not the fastest USB 3.0 drive we’ve come across, but it’s fine for normal use, especially for the money. If you’re just looking for a USB flash drive that works well with both new and older devices at a reasonable price, this is the one to go for.

Best USB 3.0 Flash Drive: Patriot Supersonic Rage Elite

Best USB 3.0 Flash Drive: Patriot Supersonic Rage Elite
  • Capacity: 64GB-1TB
  • Compatibility: USB-A 3.1
  • Speed: 400Mbps read, 200Mbps write
  • Extra features: Rubberized housing, range of colors

A USB 3.0 Flash Drive transfers files more quickly than its 2.0 predecessor and can speed along at a maximum (theoretical) rate of 5 gigabits per second. With the Patriot Supersonic Rage Elite having transfer speeds of up to 400 MB/s and storage ranging from 64GB to 1TB, this flash drive lives up to its Supersonic name. 

This model also has a rubberized housing for increased durability, with a slide mechanism to protect the USB port and stop dust and debris from entering. It also comes in a range of colors. When speed is a top priority, the Patriot Supersonic Rage Elite should have you raging to pick one up.

Best-Designed USB C Flash Drive: Samsung Duo Plus

Best-Designed USB C Flash Drive: Samsung Duo Plus
  • Capacity: 32GB-256GB
  • Compatibility: USB C, USB-A 3.1
  • Speed: 200-400Mbps read, depending on model
  • Extra features: Water-resistant

Thanks to its USB C connector on one end and USB-A adapter slotted neatly into the other end, you’ll be able to use the Samsung Duo Plus with just about any computer or non-Apple phone.

It’s an attractive device, as these things go, but that doesn’t mean it can’t handle a bit of mistreatment thanks to a water-resistant design. Sleek and compact, this drive is is a great choice for travelling professionals or anyone else who can’t be bothered carrying extra adapters. 

You’ll typically pay a little more for it than our budget USB C pick above, but with up to 400MB/s data transfer speed and a five-year limited warranty, it’s worth spending the extra money if you can. The Duo Plus is an impressive performer, with good speeds and durability, reliability, and broad compatibility  across a range of devices.

Best USB Flash Drive With Fingerprint Reader: Lexar LJDF35

Sale
Best USB Flash Drive With Fingerprint Reader: Lexar LJDF35
  • Capacity: 32GB-256GB
  • Compatibility: USB-A 3.0
  • Speed: 150Mbps read
  • Extra features: Fingerprint reader

If security is a concern, the Lexar LJDF35 Jumpdrive has a fingerprint scanner included in its base that remembers up to 10 fingerprints.

This biometric safety feature secures your files with industry-standard AES-256 encryption and unlocks in under a second, but the accompanying app unfortunately only works on Windows computers. You can use it as a standard, unencrypted drive on other types of computer, however. 

This drive has a read speed of 150Mbps, which isn’t the fastest in the world, but isn’t bad for an encrypted drive. If you’ve got a Windows machine, the Lexar LJDF35 Jumpdrive is a secure investment for travelers thanks to both its fingerprint reader and a three-year warranty.

Best Password-Protected USB Flash Drive: iStorage datAshur PRO 2

Best Password-Protected USB Flash Drive: iStorage datAshur PRO 2
  • Capacity: 4-512GB
  • Compatibility: USB-A 3.1
  • Speed: 169Mbps read, 135Mbps write
  • Extra features: Pinpad, encryption

If you thought passwords were only for typing on the computer screen, you thought wrong! This iStorage datAshur PRO 2 has a spy-like keypad included for ultimate data protection.

The drive is one of the best options for both business and recreational travelers who care about their data security, with inbuilt strong encryption and the pinpad providing some visual deterrent to thieves.

Entering the user PIN incorrectly 10 times results in that PIN being wiped, leaving data only accessible via the admin PIN. Enter that incorrectly 10 times, and the drive and encryption key are securely wiped, making any files permanently inaccessible.

Transfer speeds aren’t as fast as standard USB 3.0 drives thanks to the overhead of the encryption/decryption process, but at 168Mbps read/116Mbps write, it’s still pretty quick. Capacity options range from 4 to 512GB, so you’ll have plenty of space to store all your important documents.

This Pro version of the drive is made of metal and both dust and water-resistant to protect you from Mother Nature. There’s also a cheaper Personal model that’s made from sturdy plastic and doesn’t have the same protection from the elements.

We reviewed the Personal version of this drive in the past, and came away impressed.

It comes with an inbuilt keyring, so you can keep it on your keychain and take it with you on the go. Thanks to its durable metal case, you won’t have to worry about this flash drive succumbing to your abuse.

It’s only USB 2.0-compatible, so don’t expect blistering speeds, especially when writing large amounts of data. If all you need is a simple, no-fuss USB flash drive with a useful amount of storage space at a low price, though, this SamData model will do the trick.
