What are usb flash drives?

How to choose the right usb flash drive?

Here are some things to consider when you’re buying the best USB flash drives:

  • Capacity: The higher the memory capacity the more data the flash drive holds, although it will also increase the price. Consider what you need to store on it to ensure you get a suitable capacity for your needs. For instance, a flash drive under 10GB is fine for music, photos, and a few movies, but if you plan on storing lots of large files (like films and TV shows) then a higher capacity is recommended.
  • Speed: USB flash drives come in three specifications, each one impacting how quickly the device transfers data from a computer to the flash drive. USB 1.0 is the original specification and not that common these days, mainly due to its slower speeds, with USB 2.0 and 3.0 being the standard spec for most devices. USB 3.0 transfers files the quickest so is the most convenient, although it will cost more than USB 2.0.
  • Security: USB drives are very convenient for file transfers but aren’t the most secure device, with the lower capacity making it hard to implement decent encryption software. Some devices come with better security, such as a pin code to access the device or built-in encryption software, although these will cost significantly more than standard devices. Consider how secure you need it to be - it may not be too much of an issue unless you are storing sensitive information.
What is the best kind of usb flash drive in the UK?

There are three types of USB flash drive specifications available:

  • USB 1.0 Flash Drives: The original USB specification, USB 1.0 is mostly outdated but you can find some devices using this. Technically, an updated version called 1.1 knows the standard for this specification but offering transfer rate of 12 Mbps.
  • USB 2.0 Flash Drives: This specification is found on most cheap USB drives, with the fastest USB 2.0 devices offering transfer speeds up to 480 Mbps.
  • USB 3.0 Flash Drives: The best USB flash drives use USB 3.0, offering the fastest transfer speeds at up to 5 Gbps, while more recent devices use USB 3.1 that can offer transfer speeds of up to 10 Gbps. These devices are more likely to have encryption software for added security, although it’s not a given.
