Memory cards are essential for media storage and come in various formats and capacities. Memory card readers are inexpensive and compatible with many devices. External readers are cheaper to replace than internal ones. Look for compatibility with USB protocols and operating systems. A versatile reader offers many slots and connectivity options. Plug-and-play installation is preferable.
Due to their portability and ability to store large amounts of data, memory cards, sometimes also called flash memory cards, have become an essential component in media storage. These cards are available in a variety of proprietary formats and storage capacities. Over time, people who use personal computers, digital cameras, and other devices that accept memory cards may end up with numerous cards of different formats. Fortunately, most of the memory card reader models available today are inexpensive and capable of accepting many different types of cards. When buying a memory card reader, make sure it’s compatible with both the flash memory cards you use and any computers, printers, and digital media devices you plan to connect it to.
Some personal computers, printers, scanners, and audio-visual equipment have a built-in internal memory card reader. If the card reader fails, it is usually less expensive to purchase a replacement external memory card reader than to replace the original internal card reader. Either way, make sure the card reader you buy is compatible with the connectors on the host devices you plan to use it with. The vast majority of card readers have a Universal Serial Bus (USB) 2.0 connector, while some older flash memory cards and internal card reader slots use the older and slower USB 1.0 protocol. If you have a combination of cards that use both USB protocols, verify that the memory card reader is backwards compatible and capable of reading and writing to older cards.
A well-designed and versatile memory card reader offers enough card slots and connectivity options to be compatible with a wide range of digital equipment. Many budget models offer six or more slots and can support dozens of cards at once. A built-in USB cable can be handy, and card readers that have ports to accept all different types of USB connectors offer maximum flexibility. Some professional AV equipment uses FireWire interface protocol due to high speed data transfer rate and FireWire compatible card reader may be more difficult to find. Since computer desks can get crowded with equipment, look for a card reader that balances a small case design with maximum versatility and connectivity.
While the USB interface is extremely common and is theoretically compatible with all major personal computer operating systems, it is best to confirm compatibility with your computer’s operating system. This is especially true if you are using Macintosh, Unix or other operating systems. Most memory card readers do not require special drivers to be installed on the host computer, but look for models with plug-and-play installation just in case.
