Silicon Power is proud to present a new format and capacity in the SD category: SD High Capacity 4GB flash card. Demand for high capacity memory cards is increasingly rapidly as small storage-intensive devices such as mobile phones and portable video games capable of taking high-resolution pictures and playing high-quality videos become widely available. The capacity for SD 1.1 memory card in the past used to be no greater than 2GB. To solve this, the SD association released SD Specifications Version 2.0 for the capacity beyond 2 GB. With the new specifications, it is now possible to develop FAT 32 based SDHC memory card with capacities up to 32 GB. Silicon Power's SDHC 4GB card is scheduled for release in late August.
