Eye-Fi says SD Association violates its patents
Eye-Fi has claimed that the SD Association's iSDIO wireless SD card standard illegally breaches the intellectual property of Eye-Fi, the company that already makes Wi-Fi SD cards such as the Pro X2. The draft specification of the SDA that was touted as a new standard was a misrepresentation, Eye-Fi argued. It further insisted the SDA didn't follow its own rules and standards in adopting the new standard.
SD 4.0 standard outlined, due early 2011
Following an announcement from Toshiba at IFA yesterday that it has developed SDHC memory cards based on the new UHS-1 standard, the SD Association today outlined its plans for its forthcoming SD 4.0 standard. The breakthrough means that SD 4.0 can support real-time HD video playback, whether from a media player or a camcorder. The new SD 4.0 standard is based on a dual-row pin memory design that achieves bus interface speeds of up to 300MBps, or nearly three times faster than UHS-1's 105MBps.
SDXC Card Format
The SD Association today revealed first details of SDXC (Secure Digital Extended Capacity), its sequel to the current SDHC standard for flash cards. The format uses the exFAT file system to dramatically increase the maximum storage space from the arbitrary 32GB of SDHC to a full 2TB and would be enough to hold roughly 4,000 RAW photos or 60 hours of HD footage. Notably, the format also no longer sacrifies speed in the process, according to the organization. Unlike SDHC and other card formats, the fastest speeds should be possible even at the 2TB limit.
