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.
Lanyard hole
A hole in the body of the flash drive that allows you to securely fasten the drive to the strap and wear it as a key fob. As a rule, the
eyelet for the strap is located on one of the ends of the flash drive body (on the side or in the center).
Manufacturer's warranty
Manufacturer's warranty provided for this model.
In fact, this is the minimum service life promised by the manufacturer, subject to the rules of operation. Most often, the actual service life of the device is much longer than the guaranteed one. But an indicator of
5 years suggests that the flash drive is more likely to be lost or become irrelevant. You can also come across
a lifetime warranty, however, in this case it is better to drown out the details to which it applies. And anyway, it implies a certain period of time, though measured in decades. In addition to confirmation of reliability, such a guarantee allows you to contact the supplier after a while to eliminate possible problems (of course, not mechanical). But the difficulties in implementing this procedure (the representative office is located only in large cities) and the rare cases of the need for this (after all, it is easier to buy a new flash drive, with the exception of vital information on the old media) make the lifetime warranty more of a marketing ploy than a cool chip.
