Panasonic Working On 2-Terabyte SD Cards

Posted by timothy on from the never-delete-another-snapshot dept.

An anonymous reader writes "SD cards with a theoretical maximum capacity of 2TB are in development by Panasonic and the SD Association, it has been announced. The technology is called 'Secure Digital Extended Capacity', or 'SDXC', and Panasonic has announced it will soon show off a 64GB SDXC card. Using the new technology, read/write speeds are set to hit 300MBps. SanDisk and Sony are using the same standard to develop Extended Capacity cards in Sony's Memory Stick Pro and Memory Stick Micro range. SDXC utilises Microsoft's new exFAT file system — AKA 'FAT 64' — which first appeared in Windows Vista SP1, and has a theoretical file size limit of 16 exbibytes." Reader xlotlu adds a note about the "proprietary exFAT file system, which is available for licensing under NDA. There are currently no specific patents on exFAT, but its legal status is uncertain since it's based on FAT. The FAT patents have been previously upheld in court."

    No! They're working on a 2 TiB card and have a 64 GiB card just about ready. They have a theoretical limit of 16 EiB!

    Get with the times, accept the ibi!

    (Fuck ibi. 1 KB = 1024 bytes.)
    (Fuck this article. Might as well say Sony is working on a new battery that will recharge in less than 1 minute and last for days, while Intel is working on 32 nm CPUS, and later, 20 nm!)

    No, the file system may support it but the SDXC standard will top out at 2TB. [...] It's called planned obsolescence

    What are you talking about? 640k should be enough for anybody!

    Normally I'd agree. But after SDXC, they've run out of good options for acronyms.

    SDUC (Ultra) SDxC (xTreme!) SDSC (Super)

    SDPL (Plaid) They'll go Plaid
