Toshiba First With 64GB SDXC Card

It is eight whole months since we first had our hair blown back by the SDXC (SD Extended Capacity) standard in January. As the successor to SDHC (SD Higher Capacity) and bridging solutions X3 and X4 it offers potentially massive storage capacity and game changing performance. And now we're finally hearing about the first mass production unit...

Toshiba is the company first out the door promising a 64GB SDXC card which will start sampling before the end of the year with consumer shipments from spring 2010. That may sound a long way away, but given that we need to wait for SDXC compatible products and card readers to emerge it isn't exactly a problem.

As for the specs on the card itself it sounds rather good on paper with read speeds of up to 60MBps and writes hitting 35MBps. That said, as an example of SDXC this will be about as lame as they get. To put this in context, SDXC has a maximum capacity limit of two terabytes of data - yes, 2TB. As for performance, this can hit write speeds of 104MBps with reads managing an incredible 300MBps. Yes, it'll be the format to gel with next generation SSDs.

As I mentioned SXDC will need need hardware to take advantage of its immense potential but it will at least be backwards compatible with X3, X4, SDHC and SD cards. So while the Toshiba card is nice, don't expect it to hold onto a lead for long. Then again, with technology what does?

Speaking of which: goodbye CompactFlash...

Aw, poor CF, don't listen to the nasty man :)

I remember the first CF card I bought - a 48MB Simple Technology model for my Psion 5. Just dug it out of my Psion 7 to check the manufacturer :D

I've been following this story since it was first mentioned in January and made me practically orgasm over my shiny Mac keyboard at the mere thought of 2TB of storage on such a small device. Last year, I put all my movies & TV shows on 4TB of external Iomega drives for my Mac Mini media centre and marvelled in the compactness having got shot of so many DVDs. Now what are the chances of buying 2 of these cards at maximum capacity and plugging them some tiny USB card reader tucked out of sight? <<clean knickers on stand-by>>

^ Haha!!

2TB on this little thing??? Man, that's mind blowing! I dread to think how much that will cost.

More silly cards with none-compatible readers... At least for all the flak Sony gets, they designed the MS Pro with high capacity in mind. This is the third revision of the SD spec that isn't backward compatible...

The standard file system for SD XD will be exFAT, a proprietary Microsoft file system. So apparently, you need to buy a license from MS if you want to develop and distribute an exFAT compatible device. I guess that applies to Linux distributions, Linux-based hardware that accesses exFAT (e.g. digital picture frames) as well as other devices, like, uh, cameras.

SDHC is Secure Digital High Capacity is it not?

By "backwards compatible" do you mean the new hardware will be SD compatible? The other way round makes no sense...

Now, what happens if you put eight of these in a single box, configure them as RAID0 and then add a really fast storage controller? That has been done with SDHC and CF, and would be bloody fast... :D

@morsch: if SDXC cards are going to be at all popular, they will be able to use whatever file system you want. Just because SD cards are typically FAT/16/32, doesn't mean they have to be. The file system and the hardware should be fairly independent.
