Is it a 4GB SD or 4GB SDHC Card?

People always refer to the card as a 4GB SD, but did you know that the name is really a 4GB SDHC card. There is some amount of confusion between the 2 different formats. These cards are the same thing as SD (Secure Digital) and SDHC (Secure Digital High Capacity) have the same size and shape. What separates the two formats is that they both have different storage sizes.

SD cards – Have the ability to hold music, pictures and video from 64MB – 2GB.

SDHC cards – Have the ability to hold 4GB – 32GB worth of music, pictures and video.

The confusion between the cards is due to the fact that SD cards have been on the market for over 10 years. During that time people, people have come to associate memory cards that size as SD. When the new format SDHC was released, they still called it SD. So in reality, if someone asks for a 4GB SD, technically that card does not exist, as there is only a 4GB SDHC card that exists.

**You should take note that if you have a digital device that only uses SD cards (often older devices), then more than likely SDHC cards will not work in them. The only way it will be able to utilize the SDHC card is if the manufacturer updates the firmware. If you have plans on buying a memory card, ensure you read the manual to see what card will work with the device.

Best Place to Get 4GB SDHC Cards

If you are looking for a 4GB Secure Digital High Capacity Memory Card, then the best website to get this item has got to be Amazon.com. The reason why we love this website is the fact that you are able to get SDHC memory cards at some really low prices. This site is also pretty amazing, as they also offer FREE SHIPPING on a large variety of the products that they sell. At the end of the day, what this translates to is even more savings for your pocket.

EBay – We used to like eBay, as they have some the lowest prices anywhere when it comes to memory cards. Even though you can get some pretty good deals on the memory cards on this site, I highly recommend that people STAY AWAY FROM THEM. We have seen too many complaints from individuals about counterfeit memory cards on the website. It seems as if sellers are taking some of the smaller memory card sizes and re-formatting them to make them look bigger than they really are. Because people are getting duped, it is best to purchase memory cards from a website that is reputable and does not have these problems.
