There are a few things to keep in mind when you’re shopping for USB flash drives, and we also have some tips for using them. Compatibility: Many flash drives will work with any device with the relevant USB port, but check compatibility to avoid disappointment. Connectors: Most flash drives have USB-A connectors, but you can also get drives with USB-C, MicroUSB, and Lightning connectors. Security: Remember that USB drives can cause security issues, particularly for businesses, and you should never plug in random drives you find lying around.
