    I have quite a number of Sandisk flash drives, 1GB all the way up to 512GB. They always work and don't overheat even when transferring large amounts of data to or from them.

    I like USB drives that don't have removable caps, as they always get lost. This one fits the bill. In addition, it has encryption capabilities so if it goes missing, no prying eyes.

    So you get a really fast transfer rate when paired to a USB3 port. It does tend to slide out of the case when carried in your pocket on a keychain. For 30 bucks its hard to go wrong with it.
