SD Card Reader

Secure Digital (otherwise known as SD) is a memory card format. These memory cards are a type of technology known as non-volatile, simply meaning that they can store information even when not powered. Originally developed by the electronics companies Toshiba, Matsushita, and SanDisk, SD Cards are used to store information from portable devices such as handheld computers, digital cameras, PDAs, media players, mobile phones, GPS receivers, video game consoles and almost every other small electronic device imaginable.

SD cards are portable, re-recordable, and handy in that they can hold anywhere from 4 MB to 4 GB in disc space. The high tech SDHC format, though not without its downsides, can hold up to 32 GB of information. SD cards were originally designed to compete with Sony’s Memory Stick product. The SD card’s proponents played hard, creating the SD Card Association to promote SD cards and counts some thirty high tech companies among its members. The SD card triumphed over the Memory Stick format, and now due to the format’s increasing popularity, SD technology is rapidly advancing. The microSD represents some of the newest SD card technology. As of 2008, the microSD was the smallest SD card on the market and had the highest capacity relative to its size. MicroSD cards were originally produced by SanDisk.

SD card readers have had their share of problems. With the advent of a new SD card format, the SDHC (a format able to hold more than the once-standard 4 GBs of memory), some older SD card readers have been found to be unable to read the new SDHC format. Because SDHC format cards have the same size, shape and physical appearance as the older SD card format, and also fit into older SD card readers, this issues has caused extreme confusion and downright annoyance among some customers. Keep in mind when purchasing that SDHC technology requires a newer SD card reader and plan accordingly.

Still, SD cards, and by extension, SD card readers, have become ubiquitous in consumer technology these days. They are popular in any sort of application that needs to store a lot of information in a small space. They have become the go to memory storage device for electronics with capabilities as SD card readers, such as cell phones, PDAs, digital cameras, digital audio players and notebook computers. The key with SD cards is that they are only used in small devices where a medium amount of storage is needed. A desktop computer, for example, probably would not have a SD card reader on board simply because it would generally need to hold more memory than an SD card would allow and a hard driver is always a better option. On the other hand, when portability is a factor, such as in the aforementioned cell phones, PDAs, etc., then SD cards are an almost unbeatable solution.

To quickly and efficiently manage information from SD cards, consumers can purchase a device called a SD card reader. These small devices attach to a computer’s USB 2.0 port and allows you to transfer pictures, music, video and other data between flash memory cards and your desktop or laptop computer. Because these devices are designed specifically as SD card readers, they do not fall prey to some of the format incompatibilities you might run in to when trying to transfer information from an SD card to another device. Even better, with SD card readers, both portable devices do not have to be present to transfer information. This is not the case when transferring information via USB cable, and that can lead to annoyances if both electronic devices are not readily available at the time you wish to transfer information.
