There are a few things to keep in mind when purchasing a USB flash drive, as well as some tips for using it.
Space: To determine how much space you need, first check the size of the folder or file you’re copying. Each USB drive in the guide has a stated capacity, but the available storage will be slightly less because the device’s firmware requires space.
Speed: USB standards are constantly evolving, so we recommend at least USB 3.0, but higher is better. Although USB standards have different theoretical maximum speeds, it is important to check the read and write speeds specified by each drive manufacturer. If you primarily transfer data, you should look for a drive with high write speeds. If you plan to launch software on your computer (such as video games) through the drive, you’ll need a model with higher read speeds. Manufacturers list average speeds, but most drives tend to be much faster at transferring large files and much slower at transferring small files.
Compatibility: Many flash drives will work with any device with the relevant ports, but check compatibility to avoid disappointment. USB on-the-go (OTG) support is required when using the drive with either an Android device or the latest iPhone 15 series. Most Android devices support USB OTG. A notification will appear when you insert a flash drive with options that include file transfer. If you’re unsure, you can try the USB OTG Checker app to check support. Apple’s early iPhones and iPads don’t support USB OTG, but you can install companion apps for drives such as SanDisk’s iXpand series.
Connectors: Most flash drives have a USB-A connector, but drives with USB-C, MicroUSB, and Lightning connectors are also available. If you want to use a flash drive with your smartphone or computer, connect it to both types of connectors you need. You can also purchase USB hubs with multiple ports or adapters, but you should pay close attention to the standards supported. Otherwise, data transfer speeds may be limited. For example, this Anker USB-A to USB-C adapter is USB 3.0.
Security: Remember that USB drives can pose security issues, especially for businesses. Don’t just randomly connect drives that are lying around. If you plan to store sensitive data on a flash drive, consider biometric or passcode protection and consider the level of encryption provided. There are software services that provide encryption and allow you to password protect files on a USB flash drive.
