The maximum speed of reading data from the drive. The
higher this speed, the faster you can rewrite information from a flash drive to a computer disk, which is especially important when working with large amounts of data. In fact, the reading speed depends on a number of factors, including the interface bandwidth (see Connection interface), the design features of the drive and computer, the software used, system load, etc.
The presence
of water protection flash drive. Also in this paragraph, the specific level of such protection according to the IP standard can be specified, where the first digit is responsible for dust protection, and the second for water protection. The higher the number, the better the level of protection. So, the water protection indicator of 7 already allows us to talk about the short-term water resistance of the model. However, in most cases, manufacturers do not conduct global tests and do not mark their devices with an IP level, only assuring about some kind of protection. What it really is remains a mystery.
