Camcorders that can fully utilize a removable SDHC memory card are some of the fastest growing markets in electronic products. Until recently camcorders could only use SDHC storage cards for still images. With older designs, hard drives, DVD player, as well as tape drives were typically the equipment used to store video recordings.

“SD” means Secure Digital. “HC” means High Capacity. Aside from Sony, all other manufacturers make use of a SD or SDHC storage device with their flash memory camcorders (Sony features its own exclusive design). Sandisk, a big manufacturer of flash storage cards, has even begun marketing certain SD and SDHC flash cards as “video” cards.

All memory cards really aren’t created equal. Whether it’s called a video card or an SDHC memory card, there are distinctions among SDHC flash memory cards you ought to be familiar with before buying one.

SDHC Memory Card Interoperability

A camcorder that claims it works with SDHC flash memory cards always works using an SD card as well; on the other hand, it does not apply the other way around. If the video camera states it functions with SD cards, then that’s all it functions with; it cannot be used with a SDHC memory card. That is the exceptional case. Most modern camcorders can work using both.

Some of the cheap camcorders won’t handle all SDHC memory card capacities. Just because your video camera is SDHC compatible does not mean it functions using sizes at the upper end of the range. You would need to look at the documentation to confirm it works with 16GB SDHC class 10 or under or 32GB SDHC class 10 or under

SDHC Memory Card Capacities

SD memory cards top out at 2GB of memory capacity. An SDHC storage device can vary from 4GB to 32GB in size. More capacity means you are able to store more video and images. If you’ve got one of the new high definition camcorders you will need to get an SDHC memory card. If you’ve got a standard definition video camera you can most likely get by using an SD memory card.

SDHC Memory Card Classes

Slower SD or SDHC flash cards are probably not able to keep track of the massive quantity of data a high definition digital video camera can feed into the flash memory card. If your SDHC flash memory card is too slow your camcorder might not be equipped to record anything.

To understand this, an SD or SDHC memory card is assigned one of 4 classes to indicate its lowest speed: classes 2, 4, 5, and 10. The higher the class, the faster the flash memory is. The class indicates the minimum number ofmegabytes per second (MBps) of the flash memory; the rate it can store video recording data. Class 4 is rated at 4 MBps, class 6 is rated at 6 MBps, and so forth. You can expect to pay a correspondingly high price for a high class SDHC flash memory card.

Frequently the exact speed of a SDHC flash memory card is higher than its class. Moreover, video camera manufacturers, as well as manufacturers of other SDHC based gadgets, can design devices that need faster data transfer rates than the nominal speed indicated by the class. Because of this it is best to think of class as a general classification for comparison purposes, however, you should certainly check with the particular requirements of your device before purchasing a specific SDHC memory card. Don’t count entirely on class.

Some brands list the speed of the video camera plainly on the outside of the box while some might stuff it into the fine print of the manual. No matter where it happens to be, you ought to consult this important specification before selecting a SDHC flash memory card.

If you have a standard definition video camera, either a SD or SDHC memory card of class 2 should do the job. The best quality video you can record plays effectively with this class of SDHC flash memory card.

Your best choice for a high definition camcorder is going to be a class 6 SDHC flash card. A class 10 SDHC flash card ought to perform, depending on how tolerant to specification limits your camcorder and SDHC memory card are made. Ensure your camcorder can go that fast before paying the extra money it costs for a class 10 flash card.
