Total storage capacity. The larger it is, the more information can be simultaneously written to a USB flash drive. For comparison: the size of text documents rarely exceeds 1 MB, audio files and photos usually take several megabytes, short videos — several tens of megabytes, and a DVD-quality movie has a volume ranging from one and a half gigabytes and more. On the other hand, the price of the drive directly depends on this indicator. Thus, many manufacturers have flash drives similar in basic characteristics, differing only in volume — this makes it easier to choose the option that is optimal in terms of price and capacity.
Now on the market there are flash drives with the following volume:
4 GB,
8 GB,
16 GB,
32 GB,
64 GB,
128 GB,
256 GB,
512 GB and more.
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 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.
