Sdxc Support?

[invinciblegod]

So will there be SDXC support? 2 terabytes sounds like a storage dream come true! though i have no idea what this exfat is.

 

[Phawx]

I doubt it, We might be limited by 64GB max

It might be too early to tell if you can hack SDHC slots to except SDXC cards

I don't know about the store being usable in the slots, but alternative filesystems like UFS or ext2/3 are going to be available. UFS should work on most desktop/laptop computer OSes and should be available on the Pandora as an option. exFAT's not going to be likely unless it's a rational and logical expansion of FAT32 such that there's no potential patent infringement issues with it.

I dont know how often it was mentioned before, but the Linux SDHC Driver already has support for the theoretical maximum Size of 2 TB build-in :rolleyes:

assuming that SDXC is nothing else than unlocking the 6 bits unused in SDHC, yes, that's it. but do you know that this is the case? or did they revamp the specs completely? is it electrically compatible?

 

[Yigguth]

I hope it's compatible

I would have thought it would just be a software upgrade, theres no reason to change the hardware. The changes made to support SDHC already increased storage capacity by 512 times, and 512 times the old non-SDHC maximum size (4GB) = 2TB.

Of course, SDCard.org has always said you should use FAT for file system, so that will have to change, as I don't think it supports 2TB partitions.

Gizmodo's article mentions something about a new format (exFAT)

I'm pretty sure 2TB is the limit for FAT partitions, but I'd never actually use it for a partition that size. The 4GB file size limit is a more pressing concern at that point, since I'd presumably be putting some pretty big files on a 2TB SD*C card.

I don't know much about exFAT, but I do know it's a formatting option in Vista.

2TB? Seems like an awful lot.

 

[dj51d]

I haven't found a whole lot of information out there about exFat yet, but apparently the max file size is 16 exabytes

[Pseudonym]

Reading the article dj51d found, ExFAT is proprietorially owned by Microsoft, though licensing status is unclear. that might (will) be a problem.

 

[Ryuu]

fat is patented? :huh:

FAT64

What I wonder about is how long will the cards last? will they be "Better" than SDHC cards? I Mean how many read and writes can we expect form these new cards?

I doubt that will change, as it still depends on the nand memory the data storage will depend on.

this reads like there will be major revisions to the standard. note that they say the slots will be backward compatible. or is this just blah-blah and only software needs to be updated?

 

[Zeno Arrow]

Even if the Pandora doesn't get SDXC support for some reason (e.g. licensing), I'd think that the existence of this format will encourage those in charge of the SDHC format to release the higher capacities sooner, so it's all good.

Sounds like "Software needs to be updated, Hardware needs to be updated if you require the higher 104MB/sec speed".

I'll be very suprised if you can't run a SDXC card at SDHC speeds.

Heh... I can envision many people getting some pretty hi-definition pr0n at that point...

On a more serious note, though, the only things I can envision needing that much filesize right at the moment is for things like DVD5/9 ISOs, rips of DVDs to XiviD or h.264, that sort of thing. I'm not QUITE sure what they've got in mind for the new storage format here unless they're intending to actually be more like the low-end solid state disk with it. It would do that and this would make sense for devices like netbooks and our stuff, while being interoperable with other devices needing that sort of capacity.

It's an undisclosed expansion of the FAT format. Not all too much is known about it or if they've still got patent gotchas involved with it. You CAN use FAT32 on these devices, but it's painfully inefficient on them because of limitations on the FS such as the 4G filesize barrier, etc.
