Panasonic Working On 2-Terabyte SD Cards
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."
This article is absolute blithering bullshit. They're talking about the interface / file systems' _addressable_ size. Compared to actually achieving higher storage densities, that's about as hard as pulling a number out of the air. It has absolutely nothing to do with the technology needed to fit 2TB or any other number of bytes into whatever little card.
And oooh theyre making a 64GB card but "working on" a 2TB card? Yeah right, so only a 30-fold increase in density left to go!
Then he goes on to discuss throughput as if that has anything to do with it....
The only, ONLY good thing about FAT is that it is very well understood and supported everywhere. Why on earth would someone license a proprietary filesystem based on an awful filesystem when they don't need to?
Oh, and why on earth would a SD card manufacturer need to license a filesystem in the first place? It's not like it'll care what data is on there.
SJW n. One who posts facts.
But it died on the table.
Please forget what i just said. I am wrong so so wrong.
Since everyone is getting rid of DRM anyway would it not be a good idea to drop the SD standard altogether and continue where MMC left off? a bit like the way Sony are getting rid of MagicGate
SD is just a RIAA-approved version of MMC with extra DRM features added. Maybe I'm just a bitter old sod but I find this continuation of the SD standard and it's DRM suspicious, perhaps they are waiting for a good time to re-introduce DRM on a massive scale and since every SD card ever made already supports it they will have no problem implementing it
I bet most the supposedly hardcore RIAA-hater nutjobs don't even realise SD has the built in DRM. They have been selling DRM-enabled cards for about 10 years now and just because the SD DRM hasn't seen any widespread use nobody batts an eyelid.
With the continual increase in the capacity of storage, exponentially decreasing cost per size, and ever increasing bandwidth to link it all together, I wonder if there is there any use worrying about piracy.
You could say piracy moved to the internet because floppy disks were useless and CD/DVD burning costly, even when it's now rather cheap. Generally piracy has been scaling with availability of bandwidth and storage. But is there a point where it gets so stupidly cheap and powerful that old world business models become completely untenable?
After logging in slashdot still does not take you back to the page you were on. It's been that way for 20 years.
Given that ZFS has been optimized for flash, why bother with FAT?
Says Wikipedia "the SD 2.0 standard in SDHC uses a different memory addressing method (sector addressing vs byte addressing), thus theoretically reaching a maximum capacity of up to 2 TB (2048 GB). However the SD Card association has artificially defined the maximum limit of SDHC capacity to 32 GB"
Sounds like another way to extort people into using MS only standards. Hooray!
That's almost enough to store a picture of yo mama!
It's not a bug, it's a lepidopter!
