Sometimes you may wonder how your pen drive works. If yes then read the next few lines and it will improve your understanding about this mini miraculous thing.
Pen drive is a ROM non-volatile memory i.e. data is not lost even if power failure occurs. The data is stored in the form of array of transistors. This array of transistors is called as the cells. Each of these cells stores at least one bit of information traditionally. Let us not go into the structural details because they are pretty boring (Still if you want to read those Click here).
USB (Universal Serial Bus) Pen Drive follows tree based architecture to insert and retrieve data such that we can perform only one write operation at a time effectively. If we try to write two different files at the same time they will take more time than the sum of individual write times.
But again the writing speed is very anomalous itself. If you observe carefully a 700 MB movie takes less time to get copied than a 100 MB (100 images) file.
These screenshots prove that easily. P.S.: Copying Speed.
Now I will try to explain in a layman’s language why this happens. Let us suppose we have a bag of 5 kg and a worker. If I ask that worker to move that bag from a table to the floor he will do it in some seconds. But if I ask him to put some 50 apples from a table on the floor, it will take more time, because every time he will think about selecting an apple and then he will pick one and put it in place. Again and again he has to make that choice which will reduce his working speed.
To put it in simple words, if a file content is more in number it will take more time to get copied than a single file of same or maybe more size.
