The SD & SDHC memory card is a highly secure stamp-sized flash memory card, which can be used in a variety of digital products: digital music players, cellular phones, handheld PCs, digital cameras, digital video camcorders, smart phones, car navigation systems & electronic books.
To support the higher capacity needs, SD cards are now requiring a different design. The new SD 2.0 specifications
- which supports 4GB & up
- is called Secure Digital High Capacity (SDHC). The SD Association has created & defined 3 speed classes to help you identify speed & performance capabilities/minimum requirements of SDHC cards & their SDHC host products. Details on the SD 2.0 specification: http://www.sdcard.org or www. San Disk.com/SDHC.
Cards address data (read & write) at numerous speeds. Many factors impede this performance. SDHC guarantees a minimum read & write speed necessary to handle recording high quality video & audio. The maximum card speed may vary, but you can always depend on SDHC cards to meet your SDHC host product’s high quality performance requirements.
Featuring frustration free packaging it is now quick & easy to get to your card on delivery for instant use with no hassle of searching for a pair of scissors to open sealed plastic packaging. Less packaging means it is environmentally friendly too!
Because SDHC works differently (supports the new higher capacity cards) this new card format is not backwards compatible with legacy SD format host devices.
