Camcorders that fully utilize a removable SDHC memory card are some of the fastest expanding markets in electronic devices. Before just recently camcorders could just use SDHC storage cards for still photographs. In older designs, hard disk drives, DVD, and video tape drives were usually the gadgets utilized to store video recordings.
“SD” means Secure Digital. “HC” means High Capacity. Other than Sony, all the manufacturers use a SD or SDHC storage device for their flash memory card camcorders (Sony has its own proprietary design). Sandisk, a major manufacturer of flash memory cards, has even started promoting certain SD and SDHC flash cards as “video” cards.
All memory cards really aren’t created equal. Regardless of whether it’s called a video card or an SDHC memory card, there are distinctions among SDHC memory cards you ought to know about before purchasing one.
SDHC Memory Card Interoperability
A camcorder which says it functions with SDHC flash memory cards always works with an SD card too; on the other hand, it does not apply the other way around. If the video camera states it works with SD cards, then that’s all it functions with; it cannot be utilized using a SDHC memory card. That, however, is the exceptional case. Most modern video cameras can work using both.
A number of the cheap camcorders might not handle all SDHC memory card sizes. Because your current camcorder is SDHC compatible doesn’t suggest it functions with capacities at the top ranges. You will have to look at the documentation to confirm it functions with 16GB SDHC class 10 or under or 32GB SDHC class 10 and under
SDHC Memory Card Capacities
SD flash memory cards max out at 2GB of memory capacity. An SDHC storage device can vary from 4GB to 32GB in capacity. More capacities mean you can hold more video and images. If you’ve got a high definition camcorder you will want to get an SDHC flash memory card. If you have a standard definition camcorder you could probably get by using an SD memory card.
SDHC Memory Card Classes
Slow SD or SDHC flash cards might not be able to keep track of the large quantity of data a high definition digital camcorder can feed into it. If your SDHC memory card is too slow your camcorder will not be equipped to record a thing.
To better understand this, an SD or SDHC memory card is designated one of 4 classes to show its minimum speed: class 2, class 4, class 6, and class 10. The higher the class number, the faster the flash memory card is. The class number represents the absolute minimum megabytes per second (MBps) of the flash memory; the rate at which 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 higher price for a high class SDHC flash card.
Frequently the actual speed of the SDHC flash memory card is greater than its class rating. Additionally, camcorder makers, in addition to makers of other SDHC based equipment, can design devices that require faster rates of speed than the nominal speed indicated by the class. As a result of this it is best to think about class general category for price comparison purposes, however, you should check with the particular requirements of your device before buying a specific SDHC flash memory card. Don’t depend exclusively on class.
Some brands advertise the speed of the camcorder plainly on the outside of the box while others might stuff it in to the fine print of your documentation. Wherever it happens to be, you ought to consult this important specification before purchasing a SDHC memory card.
If you have a standard definition video camera, either a SD or SDHC flash card of class 2 speed should do the task. The best quality video you can record works very well using this class of SDHC flash memory card.
Your best bet for a high definition video camera is going to be a class 6 SDHC memory card. A class 10 SDHC flash card ought to work, depending on how tolerant to specification limits your video camera and SDHC memory card are designed. Be sure your video camera can go that fast before you pay the extra money it will cost you for a class 10 flash memory card.
