| Secure Digital memory cards (also known as SD Cards) are an extremely popular memory card and a very cost effective way to add additional memory to your device. SD memory cards are commonly found in mobile phones and PDA’s as well as the Nintendo Wii games console. SD cards offer fast data transfer and are usually plug and play depending on the device, so there is no need to turn it off to insert a card. And as SD cards are non volatile, they do not require a constant power supply to keep data intact SDHC (Secure Digital High Capacity) memory cards are a new type of SD card offering higher capacities (larger than 2MB), but are NOT compatible with standard SD card devices (unusually made before 2006). If you are looking for a higher capacity memory card, please ensure your device is compatible with SDHC. |
