Actually I bought this drive (64 GB) as a backup medium. I gather data at several locations and save the captured data on the stick. In this type of activity, it really does not depend on a high transmission speed. For security reasons, the data are on two different drives. At home I synchronize the contents of the two sticks. To test this stick for my needs, I use it currently as the main recording medium. So far, everything works to my satisfaction.
