USB storage device( USB flash drive) is a storage device that is used as a storage medium and connects to a computer or any other device being read by using a USB port.
Currently, the popularity of flash drives is very high, so the manufacturers of these devices are quite a lot. In order to make a mistake in choosing a flash drive, before buying it, you need to take into account some of the nuances.
Flash memory capacity
Perhaps the most important characteristic of a flash drive is the amount of its memory. Currently, there are flash drives, with a memory of 200 megabytes to 64 GB( there are more, but there are less such drives).Greater popularity is enjoyed by accessories with a memory capacity of 4 to 8 GB.
If you are too little versed in all these "volumes", then when choosing a flash drive, it is worth taking into account that for 1 GB of memory, you can record about 1 movie, in AVI or MPEG( very good video image quality).
And also on a flash drive with a memory capacity of 1 GB, will fit about 180 songs. If, however, this device is necessary for you to store, any text documents, then the amount of memory for you is not a key characteristic, as, as a rule, such files take up very little space.
Determined with the speed of the usb-device
The second no less important characteristic of any flash-drive is the speed of its operation. It depends on it how fast the information from your flash drive will be transmitted to the reader and back. With such accessories, the speed of information recording and the speed of reading are different.
Optimal reading speed is considered to be within 5 to 7 Mbit / s, and reading speed is 8 to 10 Mbit / s. Therefore, before buying a flash drive, try to find one that has similar characteristics. But, of course, the higher they are, the faster information will be transferred to your USB drive and back.
The speed of writing and reading, entirely depends on the specifics of the transmitted information. If this, any text documents, then, perhaps, any modern flash drive, is able to record them in a matter of seconds. If you need to transfer any multimedia files, it is advisable to choose a USB flash drive with a faster write and read speed. Otherwise, such files will be recorded for a very long time.
You should also pay attention to the interface of your accessory( USB 1.1 or USB 2.0).It's best if it's USB 2.0.This will ensure you a great speed and quality of work with the flash drive. However, before doing this, make sure that you have support for such an interface on your computer.
Which chassis and method of closing the connector to choose
There are also flash drives that are resistant to any operating conditions. The cases of such devices are made of metal or rubber. Due to the fact that they have anti-shock and water resistance, it can be said with certainty that the information stored on such a flash drive is protected quite well.
Pay attention also to how the USB connector hides. In some devices, it just closes the cap, and sometimes hides inside the flash drive. In the second case, with frequent use, the mechanism of the departing part comes into disrepair. Therefore, much better, those media, the USB connector of which is closed with a cap.
