There are a few things to keep in mind when shopping for USB flash drives, and we also have some tips for using them.
Capacity: To decide what capacity you need, first check the size of the folders or files you want to copy. Each USB device in our manual has a specified capacity, but the usable storage space will be a little less than that, as the firmware of the device requires space.
Speed: USB standards are constantly evolving and we recommend USB 3.0 as a minimum, although higher is better. While USB standards have different theoretical maximum speeds, it is crucial to check the read and write speeds that the manufacturer claims for each device. If you are mainly transferring data, you will want to look for a high-end device write speed. If you plan to run software on a computer through the device (like a video game), then you will want a high-end model Read speed.
Compatibility: Many flash drives will work with any device with the appropriate port, but it’s worth checking for compatibility to avoid disappointment. If you want to use a device with an Android device, it will require USB on the go (OTG) support. Most Android devices support USB OTG. You will be notified when you insert a flash drive with options that you need to include File transfer. You can try the USB OTG Checker application to confirm support if you are unsure. Apple’s iPhone and iPad do not support USB OTG, but you can install a companion app for devices such as SanDisk’s iXpand series.
Connectors: Most flash drives have USB-A connectors, but you can also get devices with USB-C, MicroUSB and Lightning connectors. If you plan to use a flash drive with your smartphone and computer, the easiest solution is to grab one with the two necessary types of connectors. You can also purchase USB hubs with multiple ports or adapters, but pay special attention to the supported standard or this may limit the data transfer rate. This Anker USB-A to USB-C adapter, for example, is USB 3.0.
Security: Remember that USB devices can cause security issues, especially for business, and should never turn on any devices you find lying around. If you plan to store sensitive data on your flash drive, then consider biometric or password protection and consider the level of encryption it offers. There are software services that offer encryption and allow you to password protect your files on any USB flash drive.
