When shopping for USB flash drives, there are a few key factors to consider. Additionally, we have some helpful tips for making the most out of your USB drives.
Capacity
Determining the capacity you need is crucial. Check the size of the folders or files you plan to copy. Keep in mind that the usable storage on a USB drive may be slightly less than its stated capacity due to firmware requirements.
Speed
USB standards are constantly evolving, with USB 3.0 being the recommended minimum speed. Higher speeds are preferable. Different USB drives have varying theoretical maximum speeds, so it’s essential to check the manufacturer’s stated read and write speeds. High write speeds are ideal for data transfers, while high read speeds are better for launching software. Most drives transfer large files faster than small files.
Compatibility
Ensure your flash drive is compatible with your devices. Android devices and the latest iPhone 15 range require USB on-the-go (OTG) support. Most Android devices support USB OTG, confirmed by using apps like the USB OTG Checker. While Apple’s earlier devices do not support USB OTG, apps like SanDisk’s iXpand series can be used as companions for drives.
Connectors
Most flash drives feature USB-A connectors, but USB-C, MicroUSB, and Lightning connectors are also available. For versatility, consider getting a drive with multiple connector types to use across various devices. USB hubs with multiple ports or adapters are also options, but ensure they support the required standards for optimal data transfer speeds.
Security
USB drives can pose security risks, especially for businesses. Never plug in random drives as they may compromise your data. For sensitive information, consider USB drives with biometric or passcode protection, and look for drives with encryption features. Encryption software services can also provide added security by password-protecting your files on any USB flash drive.
