What Is a SanDisk Card Reader?
SanDisk is so popular within the memory card industry that the name is virtually synonymous with memory cards themselves. SanDisk markets a variety of accessories for its memory cards, including card readers. SanDisk card readers can be found in most electronics stores and are a worthwhile purchase if you need a way to transfer files from your memory cards quickly.

Function
-
Many cameras and mobile devices with memory cards can be connected to a computer via a USB cable, in spite of the fact that the memory cards can be removed. A card reader allows memory cards to be connected directly to the computer, allowing pictures to be transferred at much higher speeds.

Types
-
Most SanDisk card readers connect to the computer via the USB port. However, for laptops, SanDisk also markets a reader that can be inserted into a laptop's ExpressCard slot. Lastly, a FireWire card reader is available. Most of these readers are compatible with many different types of memory cards--even those that SanDisk does not manufacture.
Size
-
SanDisk card readers vary from approximately the size of a stick of gum to the size of a small book. The size depends largely on the number of memory card formats supported by the reader. The largest readers support virtually any type of memory card, while the smallest support a single type, such as Secure Digital and CompactFlash.
Benefits
-
SanDisk manufactures some of the fastest memory cards available today. If you own a SanDisk memory card, the greatest benefit to owning a SanDisk reader is that you know the reader will be able to transfer data at the full speed the card is capable of--an important detail if you have spent extra money to buy the fastest memory card you could.
Expert Insight
-
Card readers are essentially the same. As long as a given card reader supports the memory card format that is most important to you, there is little reason to choose a SanDisk card reader over it. However, it is important to look for reviews of any memory card reader that you consider buying. Some off-brand or older card readers may not be fast enough to take advantage of the full speed of your memory cards.
