Read speed
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.
Write speed
The maximum speed of writing data to the drive. The
higher the write speed, the less time it takes to transfer information from a computer to a USB flash drive, which is especially critical for large amounts of data. Just like the read speed, in fact the write speed is determined by a number of factors, in particular, the connection interface (see Connection interface), the design features of the drive, system load, etc.
Retractable connector
The USB flash drive has a USB plug that can be pulled out of the case during use and hidden in it during storage. This is convenient, first of all, because such drives do not need a protective cap, which can be easily lost; however, on the other hand, retractable connectors are considered less reliable than fixed ones.
Swivel housing
In the design of
flash drives with a swivel case, there is a bracket fixed on the outside, which rotates around the axis and closes access to the USB plug. There is no protective cap for the connector; as a result, it is not protected from dust and moisture. The basic protection of the connector is provided only against mechanical damage.
