As digital cameras with 8 mega pixels and fashionable 3G cellular phones become available on the market, memory card manufacturers have also flooded the market with a sea of small format high speed memory cards designed to be used with the latest and most cutting-edge 3C digital products.

Memory card manufacturers have all focused their attentions on the memory card speed, however, consumers should be aware that although memory cards with dual channels are faster, they are also high power consumption and suffer from potential compatibility problems.

On a digital camera with limited power supply, which memory card is truly suitable? And despite the fact that virtually all high-speed SD memory cards are SDA 1.1 compliant, however, Silicon Power 133X SD high-speed memory cards are unique among their peers.


Silicon Power 133X Ultra Speed SD memory card supports up to 2GB and can satisfy professional photographers with their needs on high speed, continuous shooting and filming.

Currently, Silicon Power's 133X Ultra Speed SD memory card has the maximum data read speed of 20MB/sec and data write speed of 12MB/sec, totally meets the SDCA (Secure Digital Card Association) 1.1 regulation without utilizing dual channel design. Therefore, Silicon Power 133X Ultra Speed SD memory card is the best choice for consumers needs, a high performance memory card on their mobile electronic device with limited power supply.


The so-called "Dual Channel" memory cards utilize both 2 identical memory IC chips and 2 identical controllers (example, two 512MB chips for a 1GB memory card) to improve the performance. Therefore, that will increase power consumption.

Similar to a PC with two separate memory modules which will consume more power, dual channel memory cards also consume more power and their improvement in performance is hardly notable in general. A memory card that sacrifices valuable power resources for intangible performance increase, may not the best choice when you purchase a memory card for your digital camera.
