SDHC Memory Card Need To Know
Camcorders that fully utilize a removable SDHC memory card are among the fastest growing marketplaces in consumer electronics. Until recently video cameras could just use SDHC storage cards for still photos. In older models, hard drives, DVD player, and tape drives were typically the equipment employed to store video.
“SD” stands for Secure Digital. “HC” refers to High Capacity. Besides Sony, all other manufacturers use a SD or SDHC storage device with their flash memory video cameras (Sony features its own exclusive design). Sandisk, a big maker of flash memory cards, has even started promoting certain SD and SDHC memory cards as “video” cards.
All flash memory cards are not created equal. Whether it’s branded 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 video camera which says it works with SDHC memory cards always works with an SD card as well; however, it is not going to apply the other way around. If the video camera declares it works with SD cards, then that’s all it functions with; it can’t be utilized using a SDHC memory card. That, however, is the exceptional scenario. Most modern video cameras perform with both.
A number of the low-priced camcorders might not work with all SDHC memory card sizes. Just because your video camera is SDHC compatible doesn’t suggest it functions using sizes at the top capacities. You would need to check your documentation to make certain it functions with 16GB SDHC class 10 or below or 32GB SDHC class 10 and below
SDHC Memory Card Capacities
SD flash memory cards top out at 2GB of storage capacity. An SDHC storage device can range from 4GB to 32GB in size. Higher capacity means you’ll be able to hold more video and images. If you’ve got one of the new high definition camcorders you will want to get an SDHC memory card. If you’ve got a standard definition video camera you can most likely make do using an SD flash memory card.
SDHC Memory Card Classes
Slow SD or SDHC flash memory cards are probably not able to keep up with the massive quantity of data a high definition digital video camera can feed into the flash memory card. If your SDHC memory card is just too slow your camcorder might not be equipped to record anything at all.
To understand, an SD or SDHC memory card is designated one of 4 classes to show its nominal speed: class 2, class 4, class 6, and class 10. The higher the class number, the faster the card is. The class indicates the absolute minimum megabytes per second (MBps) of the card; the rate at which it can accept and store video data. Class 4 is rated at 4 MBps, class 6 is rated at 6 MBps, etc. You should expect to be charged a correspondingly high price for a high class SDHC memory card.
Frequently the exact speed of a SDHC flash card is greater than its class. Likewise, video camera manufacturers, along with makers of other SDHC based devices, can design devices which require higher data transfer rates than the nominal speed indicated by the class. As a result of this it is advisable to consider class broad category for price comparison purposes, however, you should check with the particular requirements of your device before purchasing a specific SDHC flash card. Don’t depend exclusively on class.
Some brands list the speed of the video camera plainly outside the box while others might bury it in to the fine print of the manual. No matter where it is, you ought to consult this important specification before buying a SDHC flash card.
If you have a standard definition video camera, either a SD or SDHC flash card of class 2 speed should do the job. The highest quality video you can record plays nicely with this class of SDHC memory card.
Your best bet for a high definition video camera is going to be a class 6 SDHC flash card. A class 10 SDHC memory card ought to work, based on how tolerant to specification limitations your camcorder and SDHC memory card are made. Ensure your camcorder can go that speed before paying the extra money it will cost you for a class 10 flash card.
