OCZ just introduced 4GB and 8GB Secure Digital HD (SD High Capacity) memory cards with a Speed Class 6 rating.
OCZ SDHC cards comply with the new SDA 2.00 specifications to support capacities over 4GB. Adhering to the new speed ratings determined by the SD Association, OCZ SDHC Class 6 cards ensure a minimum write speed of 6MB/s. These large capacity cards are only compatible with SDHC compliant products and are not backwards compatible with traditional SD format devices. Increasingly more next generation devices will host SDHC memory.
All OCZ Secure Digital HC Cards come backed with a 3 year warranty.
