Our Top Picks for 2024

The All-Around Champion: Samsung Bar Plus (256 GB)

When it comes to balancing performance, durability, and value, Samsung’s Bar Plus series continues to impress. This sleek, one-piece curved design isn’t just aesthetically pleasing—it’s engineered for real-world durability. Samsung claims it’s waterproof, shock-proof, temperature-proof, magnet-proof, and x-ray-proof, making it ideal for adventurers and professionals alike.

In our rigorous testing, the 256 GB model delivered read speeds just shy of 400 MB/s and write speeds hovering around 100 MB/s. While these numbers might not break records, they represent reliable, consistent performance for everyday tasks. The drive’s lightweight aluminum construction includes a convenient loop for attaching to keyrings, and its slim profile ensures it won’t block adjacent USB ports.

Price: $52 | Available in: 32 GB, 64 GB, 128 GB, 256 GB, 512 GB, 1 TB

The Speed Demon: Kingston DataTraveler Elite G2 (256 GB)

For users who prioritize raw speed above all else, Kingston’s DataTraveler Elite G2 delivers exceptional performance. This drive consistently hit read speeds of 420 MB/s and write speeds of 400 MB/s in our tests—numbers that rival some external SSDs. The sliding mechanism reveals a USB-A connector while keeping the drive compact and pocket-friendly.

What sets this drive apart is its ability to maintain high speeds even with larger file transfers, making it perfect for video editors, photographers, and anyone dealing with substantial data volumes. The brushed metal finish feels premium, and the included keyring loop adds practical value.

Price: $48 | Available in: 128 GB, 256 GB, 512 GB, 1 TB

The Budget Champion: SanDisk Ultra Flair (128 GB)

Not everyone needs blazing-fast speeds, and that’s where SanDisk’s Ultra Flair shines. This drive offers excellent value for casual users, students, and anyone needing reliable storage without breaking the bank. The capless design features a sliding USB-A connector that stays attached to the drive, eliminating the frustration of lost caps.

While performance is modest compared to premium options—around 150 MB/s read and 40 MB/s write—it’s more than adequate for document storage, music libraries, and photo backups. The drive’s compact size and lightweight design make it perfect for everyday carry.

Price: $13 | Available in: 16 GB, 32 GB, 64 GB, 128 GB, 256 GB

The Rugged Warrior: Corsair Flash Survivor Stealth (256 GB)

For users working in extreme environments or those who simply can’t afford drive failure, Corsair’s Flash Survivor Stealth offers unparalleled durability. Encased in aircraft-grade aluminum with a rubberized exterior, this drive is waterproof to 200 meters and shock-resistant to military-grade standards.

Beyond its impressive build quality, the drive delivers solid performance with read speeds around 350 MB/s and write speeds near 300 MB/s. The screw-on cap might seem old-fashioned, but it ensures the USB-A connector remains protected in harsh conditions.

Price: $85 | Available in: 128 GB, 256 GB, 512 GB, 1 TB

Other Flash Drives We Like

Kingston Dual Portable SSD (1 TB) – $229

This innovative drive blurs the line between traditional flash drives and external SSDs. With a distinctive metallic red body, it offers USB 3.2 Gen 2 speeds with both USB-C and USB-A connectors (both with removable covers). In our tests, it matched its impressive 1,050 MB/s read and 950 MB/s write specifications, making it one of the fastest drives we’ve tested.

While pricey, it’s worth considering for professionals who need maximum speed in a portable package. Available in 512 GB, 1 TB, and 2 TB models.

Amazon Basics Flash Drive (128 GB) – $18

Sometimes simplicity wins. This drive features a grippy texture on its slider, making it easy to operate one-handed. The top loop is perfect for keyrings, and it’s impressively lightweight. Performance is modest but reliable, consistently exceeding the stated 130 MB/s read and 30 MB/s write speeds for larger files.

Buffalo External SSD-PUT Stick (500 GB) – $70

Another SSD-in-a-flash-drive-body contender, this Buffalo drive hit 450 MB/s in our tests and includes shock protection for drops. The sliding USB-A design and included USB-C adapter add versatility, though it’s notably chunkier than typical flash drives.

PNY Pro Elite V2 (256 GB) – $60

This sliding drive performed admirably in our tests, with read and write speeds hovering around 415 MB/s and 425 MB/s respectively. The plastic cover protects the USB-A plug, and there’s an opening for a lanyard or keyring.

Avoid These Flash Drives

Silicon Power DS72 Portable SSD (1 TB)

While the price is reasonable for a 1 TB drive with USB 3.2 Gen 2 connectors, and it hit 450 MB/s read and write speeds in our tests, the design flaw is inexcusable. The plastic connector covers require bending back and get in the way when inserting the drive—a frustrating experience that undermines an otherwise capable device.

Verbatim Dual (64 GB)

This tiny drive is cheap and offers both USB-A and USB-C plugs, but the execution falls short. Write speeds were inconsistent (60 MB/s for USB-C and 90 MB/s for USB-A), and read speeds hovered around 150 MB/s for both. It’s almost too small, making it awkward to insert and remove.

How to Eject and Format Drives

Ejection Best Practices

• Windows: Click the Safely Remove Hardware notification icon in the system tray and choose Eject. For a more permanent solution, use Device Manager to set drives to Quick Removal mode.
• Mac: Use the eject icon next to the drive name in Finder, or drag the flash drive image on your desktop to the trash.
• Chromebook: Right-click on your drive in Files and select Eject device.
• Android: Expand the USB notification to find an Eject option.
• iPhone/iPad: No eject option exists—ensure no data transfer is in progress before removing.

Formatting Guidelines

Before first use, formatting ensures optimal performance. Almost every device recognizes FAT32 format, but it limits individual files to 4 GB. Choose exFAT for larger files. Remember that formatting completely wipes all data.

How to Get the Most From Your USB Flash Drive

Capacity Considerations

Calculate your needs by checking the size of folders or files you plan to transfer. Remember that stated capacity exceeds usable storage due to firmware requirements.

Speed Standards

USB standards continue advancing. We recommend USB 3.0 as a minimum, though higher is better. Check manufacturer-stated read and write speeds rather than relying on theoretical maximums. For data transfer, prioritize write speeds; for launching software, prioritize read speeds.

Compatibility Check

Most flash drives work with any device with the relevant USB port, but verify compatibility. Android devices generally support USB OTG. iPhone 16 and later models support USB OTG natively. Earlier iPhones require companion apps for compatible drives.

Connector Types

Choose drives with appropriate connectors for your needs. Many modern drives offer both USB-A and USB-C options. Consider USB hubs or adapters if you need multiple connection types, but verify supported standards to avoid speed limitations.

Security Features

USB drives pose security risks, especially in business environments. Never use random drives you find. For sensitive data, consider biometric or passcode protection and investigate encryption levels. Software services can add encryption to any USB flash drive.

Testing Methodology

We evaluate every drive using USB Flash Benchmark and CrystalDiskMark for precise speed measurements. Real-world testing includes playing HD and 4K movies on an LG OLED TV, making photo backups from various devices, and copying files across supported platforms. Some drives undergo additional testing as security camera backups, NAS storage in routers, MP3 music players, and game storage for retro consoles.

Our top picks undergo months of continued use for file backups to ensure performance remains consistent over time.
