I saw an interesting product the other day that was a combination of an SD card reader than a USB device. Doesn't this then mean that I will lose everything on my SD card? I am so confused! Help! When I insert my micro SD card into my newly bought card reader and put it into my laptop, then it says i have to format it. One disadvantage, however, is that when the SD reader is built in, it may not be able to read memory cards of varying sizes. These work on the same premise as the external devices. Many devices, including some computers and printers, have built in readers. These devices generally have several slots, which allows one device to be used to read several types of SD cards.Īn SD card reader is not always an external device. Individuals who have several different sizes of SD cards may want to consider a multi SD card reader. SD cards not only come with different storage capacities, they also come in different sizes and shapes. Another major difference is that some readers may not read certain cards at all.
Some do not read the data from the memory cards as quickly as others. Speed in this sense refers to how long it will take for the information from the memory card to be accessed by the other device. Speed is one feature that can differ amongst them. Every SD card reader will not produce the same results.
