Digital memory cards fit into readers on our electronic gadgets. We use these memory devices to store photos, movies, games, documents and more. Secure Digital is a proprietary flash memory card format for use in portable devices. Some SD memory card readers can read only a single, specific type of memory device, but the most useful are those that read multiple formats, such as SD cards, micro SD cards, compact flash cards and more.
Memory card readers are a popular way of copying and transferring digital files from one computer to another because they are so easy to use. You slip the memory chip into the open slot and plug the card reader into a USB port on your computer.
Flash drives are external memory devices used for transferring files from one computer to another. Flash drives do not have slots to hold memory cards because the memory is built right into the stick itself.
SD cards are postage-stamp size computer memory centers. SD cards are found in tablets, cameras, digital music players, surveillance cameras, video game consoles and other small electronic devices where space is at a premium.
Start with the kinds of memory cards your electronic gear uses. Most need card-specific readers to work properly, so look for a reader that accepts all the varieties of memory cards you’re using. These little chips look a lot alike, but there are four types, and it’s important to know the differences.
Most people save files, photos, videos and more to internal SD cards, then transfer them to their computer via an SD card reader. Make sure your reader is compatible with your computer’s operating system.
Most SD card readers connect via a USB cable that plugs into the ports on your computer. No matter the read and write speed of your memory card, transfer speeds are limited by the type of USB connector you choose.
USB 2.0 is the original rectangular port and has a transfer speed of only 480 megabits per second, slowest of all the USB types. If your need for data reading, writing and transfer speeds is modest, an inexpensive USB 2.0 card reader is a good choice.
