A Guide to Using SanDisk SDHC Memory Cards for Digital Cameras
Having the right memory card is very important for any application. Whether you use your camera for photography, shooting video, or a combination of the two, the card you use will have a significant impact on the performance of your device. Make sure that the card you choose is both large enough and fast enough for you, whether you're recording a sporting event or snapping shots of your kids playing outside.What does SDHC mean?
SDHC stands for Secure Digital High Capacity, which is one of the three different types of SD cards. The other two are the original SD and SDXC (Secure Digital eXtended Capacity). The main difference between each of these is the range of values that they can support for storage.
- SD - Able to support up to 2GB of memory, these cards are useful for storing small amounts of data or for transferring small files.
- SDHC - With greater storage capacity ranging from 2GB to 32GB depending on the card in question, SDHC cards are great for working with larger or more numerous files.
- SDXC - These cards have the largest capacity of any of the SD card varieties, with storage starting at 32GB and going as high as 2TB, which is larger than most computer hard drives.
There are three different sizes of SD cards. There is the standard size, and then there are two smaller sizes, miniSD and microSD. The miniSD cards are about half the size of the original design, but are not used for many devices; they were quickly replaced when even smaller cards were quickly designed. These smaller cards are approximately one-quarter of the size of regular SD cards, and because of this, they have a very common application in devices such as smartphones as expandable storage. Just like the regular cards, the physically smaller versions are available in various sizes, with both miniSD and microSD having versions that are SDHC, and micro also having the capability of supporting SDXC formatting. However, unlike full-size cards, they do not have the same storage capacity due to their reduced size. Even so, microSDXC cards are available in sizes up to 32GB, which is significant given the small size of the card.What should you know before buying a camera memory card?
There are several factors to consider when buying a memory card for a digital camera.
- Speed - This is one of the most important factors, because if the memory card is not able to keep up with the rate at which the device is creating data, then time will be wasted waiting for the card to catch up before you can continue taking pictures. If this were to happen during a video, then the quality of the stored file would suffer, which could ruin an otherwise great video clip and render it unusable.
- Storage - Know what your needs are, and make sure that you get a memory card that has sufficient storage to meet those needs.
