problem
1, the data line transmission rate and its thickness, is there any relationship, if there is a proportional relationship or an inverse relationship?
2. Which is faster for the transmission rate of the multimedia card reader and the transmission rate of the data line? Why?
3, why the memory is much faster than the external read and write rate, indicating the reason
4. Will the card reading rate of the multimedia card be faster than the card writing rate? Why?
Reply
1. Has nothing to do with the thickness of the data line
2. Depends on the interface speed of the card reader and card. The USB 2.0 interface is 40 times faster than USB 1.1, and USB 3.0 is 10 times faster than USB 2.0.
3. Compare the structure of the memory with the structure of the hard disk. The principle of hard disk and optical disk is similar.
4. Reading a card is faster than writing a card, which is determined by the flash chip.
