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.
Non-removable cap
A protective cap for the USB plug attached directly to the drive case. Compared to traditional removable caps, the risk of losing such a cap is several times lower — in fact, it can only be lost along with the flash drive itself.
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.
Material
—
Plastic. Inexpensive and at the same time quite practical material. Plastic allows you to create cases of almost any shape and colour — from classic to very original; yet it is strong and reliable enough to protect the flash drive during normal household use and even in some adverse situations. At the same time, the strength and impact resistance of plastic are relatively low, and in case of serious "troubles" — falling from a great height, stepping on a flash drive, etc. — such a case with a high degree of probability will be damaged. However, such situations rarely occur, and there are quite a few varieties of plastic, some of them are very durable. Therefore, this material in modern flash drives is extremely popular.
—
Metal. Metal combines high strength and reliability with a stylish appearance; flash drives made of this material look solid and are able to withstand fairly strong impacts that would damage a plastic product. Such cases can be heavier than plastic, but this cannot be called a disadvantage: the weight of modern flash drives is not so large that it creates inconvenience, and the massiveness of the product enhances the impression of solidity. But of the unequivocal disadvantages of metal, one can name a higher cost than plastic.
—
Rubber. Rubber is quite easy to work with and is suitable for creating complex shaped cases; many flash driv
...es made from this material are of the original design. The main practical feature of rubber is elasticity. This makes the case quite shock-resistant and allows you to endure strong short-term pressure without consequences (for example, if you step on the product). At the same time, rubber is somewhat more expensive than plastic, and the advantages mentioned in most cases are not of key importance. Therefore, this material is much less common.
— Skin. Leather by itself is not suitable as a body material; therefore, in this case, we are usually talking about a leather covering on a solid base — metal or plastic. See above for more details on these materials; as for the skin, this material gives the flash drive a rich and solid appearance, but it is not cheap, and from a practical point of view it does not provide any special advantages. Therefore, cases with leather inserts are the prerogative of fashion models, for which not only functionality is important, but also an expensive representative design.
— Wood. From a practical point of view, wood has no advantages over plastic, while it is noticeably more expensive and more difficult to manufacture — in particular, because special processing is required for moisture resistance and strength. The advantage of this material can be called an attractive appearance; in addition, some users consider wooden cases to be the most "green" or pleasant to the touch. As a result, such cases are rare — only in designer models of "flash drives", created in order to stand out among plastic and metal products.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).
