A minority of flash drives support biometric fingerprinting to confirm the user's identity. As of mid-2005,[needs update] this was an expensive alternative to standard password protection offered on many new USB flash storage devices. Most fingerprint scanning drives rely upon the host operating system to validate the fingerprint via a software driver, often restricting the drive to Microsoft Windows computers. However, there are USB drives with fingerprint scanners which use controllers that allow access to protected data without any authentication.[70]
We offer the most reliable and consistently top performing customizable, no minimum USB flash drives out there. With more than 25 styles and over 550 different looks, our drives are available in 4GB, 8GB, 16GB, 32GB, 64GB, and 128GB capacities–with most available in USB 3.0 from 16GB and up. We’re so confident in the quality of our drives, each one includes a lifetime warranty.
The memory in flash drives is commonly engineered with multi-level cell (MLC) based memory that is good for around 3,000-5,000 program-erase cycles,[40] but some flash drives have single-level cell (SLC) based memory that is good for around 100,000 writes. There is virtually no limit to the number of reads from such flash memory, so a well-worn USB drive may be write-protected to help ensure the life of individual cells.
In addition to providing reliable storage for information, many of these products come with security software that protects your personal data if you lose your device. The software secures files with 128-bit AES encryption and requires a password to unlock the stored information. It also features a drag-and-drop user interface that simplifies transferring and securing your data.
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.
You can get USB 3.0 speed in a compact and durable metal USB drive from Kingston for under $10. 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. Read speeds top 100 Mb/s, while write speeds are on the slow end. With a five-year warranty, a great design, and a value price, this small drive makes a perfect addition to your keyring.

Digital audio files can be transported from one computer to another like any other file, and played on a compatible media player (with caveats for DRM-locked files). In addition, many home Hi-Fi and car stereo head units are now equipped with a USB port. This allows a USB flash drive containing media files in a variety of formats to be played directly on devices which support the format. Some LCD monitors for consumer HDTV viewing have a dedicated USB port through which music and video files can also be played without use of a personal computer.
External flash drives use what's known as "solid-state" storage, which can store, back up, and retrieve data using only electronic circuits. Solid-state drives do not contain any moving mechanical parts, which enables them to access data quickly and easy. A typical flash drive allows up to 100,000 write/erase cycles before the integrity of the data starts to degrade. This translates to around a 10-year lifespan, depending on how much it is used.

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.
