SDXC Format Promises Speed 300MB / s

SDXC not forgotten with you? This is a memory card format announced about a year ago. Unfortunately this card is less popular due to - among others - the standard issue / compatibility.

However, recently reported, the standard SD memory card (Secure Digital) next generation, SD Specification Version 4:00, will be completed in the spring of 2010. This could mean that the cards will start SDXC can be bought in the early-or mid-2010. What is interesting?

Well, this card is suitable to answer the needs of high-definition video. For the promised transfer rate is 300MB / s, far above the rate of transfer of 104MB / s which is currently offered by the SD Specification Version 3:00.

To boost the speed, this card will use a new transfer scheme and also a new pin. Current parallel technology used will be replaced by serial transfer of technology, which will also be available for use in SD Input / Output (SDIO). The goal is to make primary school buses can also be used as an internal bus in embedded systems, such as mobile phones.

It is fun - but the leap is almost 3x the speed of folding - is the size and form factor of this ultracepat SD card will remain the same as before. Parallel pins also remain there. This means that (theoretically) SDXC cards will be used, writeable and readable by the old SD card reader, of course at a slower pace.
