You can't read a 64GB+ SD card in SDHC or SD card readers. You need a SDXC reader. Another example: If you have 30FPS HD video on a BD discs. You aren't allowed to have the file in progressive scan. It has to be interlaced (1080i). All because, when they were making the BD plans. 1080 30 and 60 fps couldn't be in Prograssive. Due to them wanting to save on bandwith. But now, no one gives a shit. |
64GB+ SD cards aren't an issue of technology, but of data format. SD cards use FAT16. SDHC cards use FAT32. SDXC cards use FAT64. So long as the software is able to handle the "higher" file system structure, it's fine.
In fact, all of your examples except for the BD disc issue are a matter of software, and thus can be updated by software.
BD is different, though. The limitation there lies in hardware - CD-related technology works with lasers, and the choice of laser and the structure of the actual reading apparatus limits the CD-like medium. Which is why DVDs are different from CDs, why double-layer DVDs require a drive that is able to handle double-layer DVDs, and why 4k BD is different from regular BD.
Hence why I said that technology isn't limited by hardware, for cards.
