Japanese company Sony not long ago announced an unusual lineup of USB flash. These drives are called universal, as they can work as laptops/PCs, and mobile phones with micro-USB. The drive has two sides.
On the one hand it is quite an ordinary connector for a USB connector. On the other, if you remove the cover — there is a micro-USB connector. With this device work almost all tablets and smartphones with Android OS.
In General, it is a convenient quick method of transferring files from phone to laptop and back without having to connect all these data cables or messing around with setting up a wireless connection. Apart from anything else, a flash drive of this type can be used as additional storage for your mobile device — for example, if you need to do a lot of photo or video.
Once the flash drive is filled, it can be connected to a laptop or PC, and throw all the files in there, freeing up space for future use.
Recall that Iran has discovered the oldest "stick" created 5.5 thousand years ago.
