Digital video camcorders usually use mini digital video tapes, DVDs or internal memory for storage. They usually have slots for memory cards but those are often used for still images taken using the camcorder. However, people often need a lot of extra space for storage that usual memory cards just can’t handle. This is why more and more video memory cards are being produced. These memory cards have a higher capacity, usually numbering in gigabytes as opposed to the traditional megabytes of storage in memory cards. With more storage now offered by memory cards, people can now have extra storage for their videos in a compact device that will let them store and carry it easier.

SanDisk Memory Cards

SanDisk Memory Cards

SanDisk has a range of memory cards specifically designed for camcorders. Their products range from 4GB to 32GB cards. The Video HD SDHC card offers high speed data transfer with the memory capacity of 4GB, 8GB or 16GB. This is the basic memory card optimized for high definition video recording. Delivering Class 6 video recording performance, the Extreme HD Video SDHC cards offer 20MB per second read/write speeds. It is available in memory capacities of 4GB, 8GB and 16GB.

Ultra SDHC cards are more rugged in design but they still feature the same high performance offered by the other SanDisk memory cards. This one comes in 4GB, 8GB, 16GB and 32GB varieties.

For Sony digital cameras and camcorders, SanDisk, together with Sony, has designed the Ultra Memory Stick PRO-HG Duo card. It promises the same high performance and high speed qualities of SanDisk memory cards but designed specifically for Sony devices. It comes in 4GB, 8GB, 16GB and 32GB capacities, plus a read/write speed of 30MB per second.

Being high quality video memory cards does not just mean a large storage space.
